y > 8

All real numbers

Answer 1

What do you think it is?

Answer 2

Welcome to openstudy :D

Answer 3

what's the range of the function? the value of "y"? the value of "x"?

Answer 12

Yup

Answer 13

I was thinking B too

Answer 14

Thanks :3

Answer 15

Mhm :)

Answer 16

minimum value of (x+5)^2 is zero, so minimum value of f(x)=0+8=8
maximum value of
\[f \left( x \right) is \infty hence range is \ge 8\]
