(f@g) (x)=3/ (3-2x), (g@f) (x)= (3 (x-2))/x (f@g) (x) is the same as f (g ..., Click here:point_up_2:to get an answer to your question :writing_hand:find gof and fog iffxx and gx5x2, How do you find #[fog](x)# and #[gof](x)# given #f(x)=x^2-1# and #g(x)=5x^2#? Precalculus Functions Defined and Notation Function Composition. 1 Answer Narad T. May 6, 2017 The answer is #[fog] (x)=25x^4-1# and #[gof] (x)=5x^4-10x^2+5# Explanation: This is a composition of functions. #f(x)=x^2-1# ...
