WebMath Statistics Find f(g(x)) and g(f(x)) and determine whether the pair of functions f and g are inverses of each other. f(x)=−3x and g(x)=−3x f(g(x))= g(f(x))= Determine whether f and g are inverses of each other. Choose the correct answer below. A. f and g are not inverses of each other. B. f and g are inverses of each other. WebThe inverse function is x = 4 + 2y^3 + sin ( (pi/2)y) => 0 = 2y^3 + sin ( (pi/2)y) since x=4. Therefore y=0. So the coordinate for the inverse function is (4, 0) and the non-inverse function (0, 4) So you choose evaluate the expression using inverse or non-inverse function Using f' (x) substituting x=0 yields pi/2 as the gradient. WebAn inverse function essentially undoes the effects of the original function.
