Find the vertex of the parabola.
y = 2x² + 8x + 12
a. (2,-4)
b. (-2, 4)
C
d.
(-4, 2)
(4, -2)

Correct answer is B. (-2,4)

Step-by-step explanation:

Given: y = 2x^2 + 8x + 12

if x = 2,

Use substitution: y = 2(-2)^2 + 8(-2) + 12

                                y = 8 - 16 + 12

                                   y = -8 + 12

                                       y = 4

So, (-2, 4) would be your answer.

I hope this helps!!!

the image of (6, 9) under a dilation is (4, 6). the scale factor is

47 - 90 = 43

43 - 180 = x

x = 137
