Determine whether the Mean Value theorem can be applied to f on the closed interval [a, b]. (Select all that apply.)
f(x) = 16x + 31, [-1,3]
Yes, the Mean Value Theorem can be applied.
No, because fis not continuous on the closed interval [a, b].
No, because fis not differentiable in the open interval (a, b).
None of the above.
If the Mean Value Theorem can be applied, find all values of c in the open interval (a, b) such that f'(c) -
