For the given functions f and g, complete parts (a)-(h). For parts (a)-(d), also find the domain. f(x) = 2x + 1; g(x) = 8x - 3 (a) Find (f + g)(x). (f + g) (x) = (Simplify your answer.)For the given functions f and g, complete parts (a)-(h). For parts (a)-(d), also find the domain. 4x + 9 8x f(x) = 9x - 4 : 9(X) = 9x - 4 (a) Find (f + g)(x). (f + g)(x) = (Simplify your answer.)
