Question

After finding critical points and identifying endpoints, what should be done next?

Options

• Find only local maximum values.

• Evaluate only \[f'(x)\] at the endpoints.

• Evaluate the original function \[f(x)\] at all the critical points and endpoints.

• Discard all critical points.

Answer 1

The original function values must be calculated at every critical point and endpoint. These values are then compared to identify the absolute extrema.
