Question

determine the absolute maximum value of the function $f$.

Explanation:

Step1: Identify peak points

Look at the graph's highest points. The left peak and the right peak.

Step2: Compare y - values

The left peak has a y - value of 6 (from the graph's y - axis scale), the right peak has a y - value of 4. So the highest y - value is 6.
