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

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

If g (x) = x ^(2) -1 and gof (x) = x ^(2) + 4x + 3, then f ((1)/(2)) is equal (f(x) gt 0 AA x in R)

If f(x)=x^(2)-1 and g(x)=(x+1)^(2) , then gof(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 g(x)=x^3+x-2 and g(f(x))=x^3+3x^2+4x then f(1)+f(2) is equal to ________
