Give the domain and range.
y=(x+)^27
answer:
y=(x+4)(x=4)7
y=(x^2+8x+16)7
y=x^2+8x+9
The domain and range equal all real numbers.

It looks like you mean
Give the domain and range.
y=(x+4)^27
y = x^2 + 8 x + 9 agreed
BUT
This is a parabola opening up
Indeed you can get a y for any x, so the DOMAIN is all real x
HOWEVER
The RANGE is all y above the vertex!
The vertex is at x = 4 where y = 7
so the range is all y greater or equal to 7
