Question

Which equation goes with the t-chart below?
x y
-2 10
-1 5
0 2
1 1
2 2

y= 2x^2-x+ 2
y=x^2- 2x+ 2
y=x^2- 2x- 2
y= 2x^2-x- 2

Answer 1

CHART?? @iheartfood

Answer 2

Use y=mx+b
m=slope
b= y intercept

Answer 3

You have already y - intercept (0,2)

Answer 4

It's a little more complicated than that ivettef. She has a quadratic equation, so the best way to find slope is by using the derivative

Answer 5

You are right oops

Answer 6

So do you know how to take the derivative iribeiro?
