Identify the x-value of the vertex of the quadratic equation y=−(x+7)2−10, given that the vertex form of a quadratic equation is a(x−h)2+k.

x = - 7

Step-by-step explanation:

The vertex form of a parabola is

y = a(x - h)² + k

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

y = - (x + 7)² - 10 ← is in vertex form

with h = - 7 since - (- 7) = + 7

vertex = (- 7, - 10 ) with x- value - 7
