Classwork 3/11

1) Explain a real life situation that we have talked about in class where we have used quadratic functions.

2) In your own words explain to me how we find the solutions to a system of a linear function and a quadratic function.

3) Out of everything that we have done in class the last 2 weeks what is your favorite thing?

  1. 1)a real life situation for a quadratic function would be the equation with the rocket.2)we can find the linear function and the quadratic function by graphing them at the same time to find the intersection points.3)My favorite thing was the quadratics and the xtranormal creations.

  2. 1. A situation that we talked about was the height of a rocket or how high a bullet would go if fired in the air.
    2. To find a linear function first you have to find the slope and the y-intercept of the graph from the equation y=mx+b,m=slope and b=y-intercept
    to find a quadratic you first need to hit the y= button in your calculator and type in the function then hit 2nd table and from there plot the points and you will get a u-shaped curve called the Parabola

  3. 1)when you go up an hill and you come right back down positve to negitive
    2)you put them in to the caculator hit y= them and then 2nd graph to get a table of coodanets and then after you do that you 5 eithc is intercept and there you go
    3)my favorite thing we did was when we made that movie it was so funny

  4. 1.we have talked about how a roller coaster have to do with a quadratic functions how fast it goes up and how long it comes down. 2.first we hit y=, then we write the two equation, then hit 2nd trace, then you scroll down to number 5 and click enter and you will get a graph with the interception points 3. my favorite thing was making a movie about an avatar talking about math class.

  5. 1.we talked about how a basketball have to deal with quadratic functions like how a basketball goes up and then back down
    2.i think u have to find the y-intersect and the slope
    3.my favorit thing was when we did a movie useing avatar people and we talked about linear an quadrtic functions

  6. 1)we taled about the bullet travling up then down.2)you have to graph the qudratic function and the linear function to find the intercept.3)my favorite thing was the xtranormal creations

  7. 1. we talked about rockets . how long it takes to get in the air , and how long it takes to come down

    2. you hit y= , then write the two equations . then hit 2nd graph then you hit 5 intercept then your done !

    3. the best part was when we mad the avatar movie

  8. 1-we talked about shooting a rocket up in the air and having it come back down
    3-my favorite thing was making the movie

  9. 1-The rocket was a realistic situation because we graphed how long it would take for the rocket to reach a certain height, and when it would hit the ground.
    2-You hit the "Y=" button, then graph the equations at the same time.
    3-my favorite thing was making the Xtranormal movie.

  10. 1)We used a realistic sistuation when we were talking about the rockets.
    2)You have to us y=mx+b an plot the y-intercept on the graph.
    3)My favorite thing we did was making the movies

  11. 1)We Talked About Rockets...

    2)First You Hit Y= Second You Put In Your Equations Last You Hit 2nd Graph...

    3)when We Made The Movie... It Was Fun!!!

  12. 1:When we did the rocket ship and tried too find out how long it'll go too rise .
    2: You have too use the y button on a calculator and show work on the graph .
    3:I loved making the movie .

  13. 1)we have used quadratic functions when we are graphing in the real life we used the rockat
    2)you hit the y=mxtb an plot the y intercept on the graph.
    3) making movie that is my favorite thing.

  14. 1)when we tried to see how high the rocket would go 2)you have to hit the y button put in the equations then hit second and graph. 3)when we made the movie.

  15. 1. A real life situation that we talked about in class where we have used quadratic functions are when we talked about rockets .
    2. You use a celculator and hit the y= botton and see where the intercept is on the graph .
    3. When We went on the computers and made our movies .

  16. 1.a real life situation that we have talked abou is a rocket going up into the sky from the ground and it landing back on the ground.
    2.hit "y=" and type in the equations. then hit
    "second" "graph" find the intrecepts.
    3.all of it

  17. 1)we have used quadratic functions when we are graphing in the real life we used the rocket

    2.hit "y=" and type in the equations. then hit
    "second" "graph" find the intrecepts

    3) making movie that is my favorite thing.

  18. 1.a real life situation that we talked about is rockets going up and see how many secs it take for it to land on the ground.
    2.hit y= and type in your equation hit 2nd graph and find the interceptions.
    3.finding the y intercepts.

  19. 1) One real life situation is when we talked about a Rocket shooting into the sky it comming crashing down to the ground.

    2) To find the Y-Intercept hit ( Y= and input the equations, then hit Graph and find the two intercept points.

    3) Out of everything that we have done in class in the past two weeks graphing would have to be my favorite thing that we have done.

  20. 1. a real life situation question we did is the rocket that we did on the green paper

    2.Hit y = and type in your equation hit 2nd graph and find the interceptions.

    3.Find they Y interceptions

  21. 1.a real life situation that we have talked about in class where we have used quadratic functions Is when we look for the rise and fall of the rocket . 2.we find the solutions to a system of a linear function and a quadratic function you have to graph the quadratic function and the linear function to find the intercept 3.Out of everything that we have done in class the last 2 weeks My favorite thing Was the Graphing .

  22. We graphed a rocket ship going up in the air and coming back until it hit the ground. the most fun thing we did was make the movie on the computer.

  23. )the movie was the funnest thing we have done

  24. 1.when we talked about the height of a rocket.
    2.we find the solutions to a system of a linear function and a quadratic function we have to graph the quadratic function.
    3.i like when we making movie because that's something different.

  25. 1)a real life situation about quadratic function

    2)i can find it about the graphing

    3) the movie its my favorite because its making wonderful to the student
