graph the parabola, then determine the domain and range. f(x)=x^2x4x4

assume you mean
y + 4 = x^2 4x
y + 8 = x^2  4 x + 4
y + 8 = (x2)^2
vertex at ( 2 , 8)
so range is y >/=  8
domain is all real x 
so do i write the domain as (infinity,infinity)
not sure how to write the range you showed. It has to be in interval notation
would it be (infinity,8)?
