I need assistance with this question for my notes

For the following functions f (x) m - and s (x) myx2- 4 find the following functions and their domains. Show your work separately and submit it using the assignment link on HuskyCT. Note: Write exponents using the * symbol (so -2 = x*2); write square roots using the notation sqrt() (so g(x)-sqrt(x*2-4): write fractions using / (so [(x) = 1/x) and write the infinity symbol co using the word (so - co as -infinity and co as infinity) (a) (r * g)x) = has domain (b)UgXx) = has domain (c) (g(x)) = has domain
