In the tollowing, it your answer includes more than one interval write the intervals separated by the \"union\" symbol, U, which you can type as U. It you need to enter the oo symbol, type it as inf. Given that f(z) = 22 13z and g(z) = z + 8, find and simplify the following: a. (f+9g)(z) = and the domain of (f + g) is and the domain of (f g) is b. (fg)(z) = c. (fg)(x) and the domain of (fg) is d. (%)(m) and the domain of (g) 15
