Provide an appropriate response.Let f have a derivative on an interval I. f' has successive distinct zeros at 
and 
Prove that there can be at most one zero of f on the interval 
What will be an ideal response?
Assume there are 2 (or more) zeros a and b on the interval 
where 
By Rolle's theorem there is at least one number c in (a, b) such that 
and 
This implies there is another zero between 1 and 5 which is a contradiction. Thus, there cannot be more that 1 zero of f on
