Graph of a function on the domain negative 2, 6 and range negative 3, 4. Graph increases from negative 2, 3 until 2, 0 and from 4, negative 2.5 to 6, 4. Graph decreases from 2, 0 to 4, negative 2.5. There are x intercepts at 2, 0 and 4, negative 2.5.
Find the x-value where f attains its absolute minimum value on the closed interval from x = -2 to x = 6. Justify your answer.
portion goes to 0. What is then left is:
