If f(x) = x^2 – 1 and g(x) = 2x – 3, what is the domain of (fog)(x)? (-infinity, infinity) [-1,infinity) [-5,infinity) (infinity,-infinity)

f(x) = x^2 – 1 and g(x) = 2x – 3

(fog)(x) = (2x-3)^2 -1

(fog)(x) = 4x^2 - 12x + 8

The domain is the x value, which can be any real number, so the domain is:

(-infinity,infinity)
