    critical points are those where the derivative vanishes

    f'(x)=0

    ok f we see denominator x^2 is 0,but in the up x^2+9 if we see c^2+9=0 then c^2=-9 which is 3i i dont know the solution here

    so it means that c=0 is one critical value,coz derivative is not defined there

    but do mind one thing,function should be defined at the critical value

    so what do you think the solution here , is have any critical value ?

    f(x)=9/x+x is the funtion
