Question

The equation would be: y=5x^2-7x+0

1. Create your equation using the information in the directions. State your equation.
2. Complete the table below. Show your work.
3.    Table of Ordered Pairs    x      -2     0     2 , y=?
4. State in what quadrant or on what axis each ordered pair from part b is located.
5. Graph your equation and capture a picture of the graph to post to the discussion board. You may use your graphing calculator emulator software or take a digital picture of your graphing calculator screen. The image should be visible in the textbox where you are typing your work. Do not attach it as a file. (Please follow the instructions above for inserting an image into your post.)
6. What window did you use to graph your equation?

• State in what quadrant or on what axis each ordered pair from part b is located.
• Graph your equation, capture a picture of the graph and post it to the discussion board.
• State the window used to graph the equation.

Answer 1

$y=5x^2-7x$

$y(-2)=5\cdot(-2)^2-7\cdot(-2)=34$

$y(0)=0$

$y(2)=5\cdot2^2-7\cdot2=6$

$(-2,34)$ : II Quadrant

$(0,0)$ is the origin

$(2,6):$ I Quadrant
