If f(x)=(2-x)/(2+x) , then determine f(x^(-1)) .

If f(x) =|(1, x, x+1),(2x, x(x-1), x(x+1)), (3x(x-1), 2(x-1)(x-2), x(x+1)(x-1))| then what is f(-1) +f(0) +f(1) equal to ?

If f(x)=(x(x-1))/(2), then the value of f(x+2) is-

If f'(x)=sqrt(2x^2-1) and y=f(x^2) then what is dy/dx at x = 1 ?

If f(x)=x^2+2x+1 , then: f(x-1)-=

If f(x)=(x^(2)-1)/(x^(2)+1) prove that f((1)/(x))=-f(x)

Let f(x)={(1+|x-2|,x!=2),(2,x=2):} then at x=2, f(x) has
