Describe whether Rolle's theorem applies to the function shown below on the given interval. If so, find the point(s) that are guaranteed to exist by Rolle's theorem.

f(x)=x(x-10)^2 ; [0,10]

Step 1

Given:

Describe whether Rolle's theorem applies to the function shown below on the given interval. If so, find the point(s) that are guaranteed to exist by Rolle's theorem.

Step 2

**Rolle’s Theorem**: Let *f* be continuous on the closed interval [a, b] and differentiable on the open interval (a, b). If *f (a)* = *f (b*), then there is at least one number c in (a, b) such that *f’(c)* = 0.

Step 3

Now since:

*f(x)*is a polynomial function so it is continuous everywhere in the given interval.*f’(x)*is also differentiable in given open interval.*f (0)*=*f (10*) = 0.

Hence all the hypotheses are true for the given fu...
