Evaluate each of the following

Let f(x) = Va - 3 and g(a) = 2 + 3. Evaluate each of the following. f(g(9) ) f(9(5) ) 9 (f (5 ) ) = f(g( -4) ) = g ( f ( - 4) ) = If there is no answer, enter "undefined". Are the following statements true or false for general functions? ? Given two functions f and g, then f(g(x) ) = g(f (x)). ? C Given two functions f and g, then f(g(x) ) = g(f(x) ) only if f and g are inverses of each other
