f(x)= x^(2)-3x + 4 If f(x)= f(2x+1) find the value of x .

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

f(x)=x^(4)-6x^(2) find f'(x) .

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

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

f(x)=5-|x-1| . Find the maximum value of f(x) , also find the value of x for which f(x) is maximum.

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.

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.
