If f'( x ) = `x - 3/x` , then find f(x)

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

(i) If f(x) = 3x^(4)- 5x^(2) + 7, " find " f(x-1) (ii) If f(x) = x^(2) - 3x + 4 , then find the values of x satisfying f(x) = f(2x+1)

If f(x)=(x-1)/(x+1), then find f{f(x)}

If f:RrarrR defined by f(x)=x^(2)-2x+3 , then find f(f(x)) .

If f(x) = x^3 - 3x^2 + 5 , find f(0) + f(3)

If f(x)=x-9 ,then find f(x)-f(-x)

If f(x)=(7)^(x^3+3x) then find f^'(x)
