Expert Solution
Step 1

Definition:

Let f be a function  of a real variable, a critical point is a point in the domain of the function where the function is either not differentiable or the derivative is equal to zero.

 

Given f(x)= (6+5x)6 ,since this is a polynomial,this is everywhere differentiable i.e derivative always exists.
