Question

The table of values models the quadratic function y = x2 + 7x – 9. What are the missing y-values in the table for the x-values?

Answer 1

Answer:

B

Step-by-step explanation:

-19, -15, -9, -1, 9

Answer 2

The answer is letter B.

y = x² +7x-9

y= (-2)²+7(-2)-9

y=4+-14-9

y=-19

y=(-1)²+7(-1)-9

y=1+-7-9

y=-6+-9

y= -15

y=(0)²+7(0)-9

y=0+0-9

y=-9

y=(1)²+7(1)-9

y=1+7-9

y=8-9

y= -1

y=(2)²+7(2)-9

y=4+14-9

y=18-9

y=9
