Homework help asap please:
f(x) = 3/x4
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

Best ResponseYou've already chosen the best response.0f(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..

Best ResponseYou've already chosen the best response.0And 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)
