Consider the equation of parabola f (x) = - (x+7) ^2 - 10. The x - coordinate of the vertex is

-7

Step-by-step explanation:

f (x) = - (x+7) ^2 - 10

This parabola is written in the form

y = a (x-h) ^2+k

Where (h, k) is the vertex

f (x) = - (x+7) ^2 - 10 = ( - (x - - 7) ^2 + - 10

The vertex is at (-7, - 10)

The x coordinate is - 7
