function: f(x)=4(x+8)^2-5 f(x)=-5 what is x?

Question

Given function f(x)=4(x+8)^2 -5; f(x)=-5  what is x? - what points are on the graph list any x-intercepts and y-intercepts

Answer 1

- 5 =4( x + 8 )^2 - 5

-5 + 5 = 4(x + 8 )62

0 = 4(x + 8 )^2

0/4 =(x + 8)^2

0 = ( x + 8 )^2

x + 8 = 0

x + - 8
