If f(x) is a quadratic function such that f(0)=2, f(1) =3 and f(4) =42, find the value of f(5) .

Given f(x) is symmetrical about the line x=1 , then find out the value of 'x' satisfying f(x-1)=f((x)/(x+1))

If f(x)=x^(2+x+1 , then find the value of 'x' for which f(x-1) =f(x)

If f(x)=x^(2) , then evaluate: (f(1*2)-f(1))/(1*2-1)
