The graph of which equation has a vertex of (-2, 0)?

Question

Choose one answer.
A. y = (x - 2)2 + 2
 

B. y = 3(x + 2)2 + 1
 

C. y = 3(x - 2)2
 

D. y = 3(x + 2)2

Answer 1

The vertex of the graph of y = A(x - h)² + k is (h, k).

 

y = 3(x + 2)² = 3[x -(-2)]² + 0

 

The vertex of  the graph of y = 3(x + 2)² is (-2, 0).
