Homework help asap please: f(x) = 3/x-4 g(x) =(3/x)+4 Find f(g(x)) and g(f(x)), then find the f^-1(x) and check using f(f^-1(x) =x and f^-1(f(x) =x

    f(g(x)) means you take the function g(x) and plug it into the x of the function f(x), so for example if I have \[f(x) = 3x^2+5\] and \[g(x) = 9x+2\] and we have to find f(g(x)) we take g(x) and plug it into the x of f(x) so we get \[f(g(x)) = 3(9x+2)^2+5\] and then you simplify etc..

    And the \[f^{-1}(x)\] implies inverse, to do that we can follow these steps: Replace f(x) with y Switch x's and y's, so put x where y is and y where x is (originally). Solve for y Replace y with f^-1(x)

    the lasttime I tried the problem, I had f(g(x) = 3/((3/x) +4) -4
