If g(x)=x^(2)+x+x-1 and g(f(x))=4x^(2)-10x+5 then find f((5)/(4))

If g(x)=x^(2)+x-1 and g(f(x))=4x^(2)-10x+5 then find f((5)/(4))

If g(x)=x^(2)+x-1 and (gof)(x)=4x^(2)-10x+5, then f((5)/(4)) is equal to:

If g(x)=x ^2 +x−1 and (gof)(x)=4x^2−10x+5 , then f(5/4 ) is equal to:

If f(g(x))=4x^(2)-8x and f(x)=x^(2)-4, then g(x)=

Suppose f,g, R to R . If g(x) defined by g(x) = x^(2) + x-2 and (g.f)(x) =4x^(2) - 10 x + 4 , then f(x) may be given by

If f(x)=4x-5,g(x)=x^(2) and h(x)=(1)/(x) , then f(g(h(x))) is :

If f(x)=4x-5 and g(x)=3^(x) , then f(g(2)) =
