The vertex of the parabola below is at the point (1,-5). Which of the following
could be this parabola's equation?
A. y = 2x^2+5
B. y = (x + 1)2+5
O C. y = x^5
D. y = (x - 1)^2-5

Answer 1

D

Explanation:

Step 1: Solve

We use the vertex form y=a(x-h)²+k

h is the x coordinate of the vertex

y is the y coordinate of the vertex

Substitute them in to get

y = (x-1)² -5
