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) -

Tutorial Exercise
Identify the open intervals on which the function is increasing or decreasing.
g(x) = x² - 6x - 280
Step 1
To determine the intervals on which the function is increasing or decreasing, first find the critical numbers of the given
function.
Determine g'(x).
g(x) = x² - 6x - 280
g'(x)=2x-6
Step 2
To determine the critical numbers of g(x), set g'(x) equal to zero and solve for x.
g'(x) = 0
