f(x) = abs(sin(x)), -pi less than or equal to x less than or equal to pi

g(x) = x^2

let H(x) = g(f(x))

i got that H(x) would equal sin^2(x).

THIS IS WHERE I AM STUCK!

find the domain of H. do i still need to account for "-pi less than or equal to x less than or equal to pi" or is it all real numbers?
