Have a moment where I can't remember a simple process to solve a problem to determine if a pair of functions are inverse. f(x)= 5x-9; g(x)= (x+5)/9; I'm stuck on the first step. (5)(x+5)/9. I keep getting [(5x+25)/45]-9 but I know the answer, according to the text is f(g(x))=(5x-56)/9 & g(f(x))= (5x-4)/9: f and g are not inverses. I can solve the last problem(f(x))= (5x-4)/9 just not the first one.
