Question

1. complete the table.

$y = x^2 + 2x - 8$
$x$ $y$
-2 -8
0 -8
-3 -5
1 -5

Explanation:

Step1: Substitute x=-2 into equation

$y=(-2)^2 + 2(-2) - 8 = 4 - 4 - 8 = -8$

Step2: Substitute x=0 into equation

$y=(0)^2 + 2(0) - 8 = 0 + 0 - 8 = -8$

Step3: Substitute x=-3 into equation

$y=(-3)^2 + 2(-3) - 8 = 9 - 6 - 8 = -5$

Step4: Substitute x=1 into equation

$y=(1)^2 + 2(1) - 8 = 1 + 2 - 8 = -5$

Answer:

$x$	$y$
0	-8
-3	-5
1	-5
