Question

what are the critical values of f'(x)= x^2+9/x^2

Answer 1

critical points are those where the derivative vanishes

Answer 2

f'(x)=0

Answer 3

or the derivative does not exist

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

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

Answer 8

what function is actually given in this prob,u posted the derivative

Answer 9

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