Answer 1

Answer:

c. y + 2 = 2(x + 3)²

Explanation:

When we replace (x, y) equal to (-4,0), (-2, 0) and (-3, -2) on the correct equation, the equation is satisfy.

So, for option c, we get:

if (x, y) = (-4, 0)

y + 2 = 2(x + 3)²

0 + 2 = 2(-4 + 3)²

2 = 2(-1)²

2 = 2

If (x, y) = (-2, 0)

y + 2 = 2(x + 3)²

0 + 2 = 2(-2 + 3)²

2 = 2(1)²

2 = 2

If (x, y) = (-3, -2)

y + 2 = 2(x + 3)²

-2 + 2 = 2(-3 + 3)²

0 = 2(0)²

0 = 0

Since option c. y + 2 = 2(x + 3)² is satisfied in all points, the answer is c.
