Question

Enter the coordinates of the vertex of the graph of y = 2(x + 5)2 − 4.

Answer 1

coordinates of the vertex ( -5 , -4).

Explanation:

Given : y = 2(x + 5)² − 4.

To find : Enter the coordinates of the vertex of the graph .

Solution : We have given y = 2(x + 5)² − 4.

Vertex form of parabola : y = a(x - h)² + k

Where, (h,k) are vertex

On comparing it with given equation

Vertex : (-5 , -4).

Therefore, coordinates of the vertex ( -5 , -4).

Answer 2

vertex = (- 5, - 4)

Explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

y = 2(x + 5)² - 4 is in this form

with vertex = (- 5, - 4)
