Question

What is the equation of the following graph in vertex form?

Answer 1

Answer:

D. y=(x+1)2

Step-by-step explanation:

Answer 2

Correct answer is D.

Graph passes through the point (-1, 0).
Therefore, x = -1 and y = 0.

$y=(x+1)^2 \\0=(-1+1)^2 \\0=0^2 \\0=0 \;\; \text{T}$

This is the only equation which is true for x = -1 and y = 0.
Therefore, the solution is $y=(x+1)^2$
