A function is defined as `f(x)=x^2-3xdot` Find the value of `f(2)dot` Find the value of x for which `f(x)=4.`

If f(x)=x^3+2x then find the value of f(4)

Ilf f(x)={x^3, x 2 , then find the value of f(-1)+f(1)+f(3) . Also find the value (s) of x for which f(x)=2.

If f(x)=x^(3)+2x , then find the value of f(3) .

If 2f(x)+3f(-x)=x^(2)-x+1, find the value of f'(1)

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

A function f is defined by f(x) = x^(2) + 1 . Find f(0), f(5), f(10).

A function is defined as f(x)=(x^(2)+1)/(3x-2). Can f(x) take a value 1 for any real x? Also find the value (s) of x for which f(x) takes the value 2.

Find the value of f(f(-2)) , if f(x)=(x)/(x+1)

If 2f(x)+3f((1)/(x))=x-1. find the value of f(2) .
