E)The graph has no horizontal tangents.

Quizplus · Accepted Answer

Since the given function is not provided, we cannot determine the answer for sure. However, the key to finding horizontal tangent lines is to find where the derivative of the function is equal to zero. Therefore, we would need to take the derivative of the function and set it equal to zero, then solve for x. The answer choice that corresponds to the x-value(s) we find is the correct answer.
