Find the absolute extrema of the function on the closed interval f(x) = 7 − x, [−2, 3]

Question

f(x) = 7 − x,    [−2, 3] please help solve

Answer 1

The graph of the function is a decreasing straight line. It has no internal maximum or minimum point.

The maximum is at the left end point of the interval and the minimum is at the right end.
