Best ResponseYou've already chosen the best response.0\( g(x) = 5x^2 – 1\) \(f(x) = 3x^2 – x + 2\) \(f[g(x)] = f(5x^2 – 1) = 3[5x^2 – 1]^2 – [5x^2 – 1] + 2 \) this what you meant?? hope it helps :p

Best ResponseYou've already chosen the best response.0\(\bf f(x)=3x^2x+2\qquad g(x)={\color{brown}{ 5x^21 }} \\ \quad \\ f(\ {\color{brown}{ g(x)}}\ )=3x({\color{brown}{ g(x)}})^2({\color{brown}{ g(x)}})+2 \\ \quad \\ f(\ {\color{brown}{ g(x)}}\ )=3x({\color{brown}{ 5x^21}})^2({\color{brown}{ 5x^21}})+2\)
