For each interval, use Figure 4.40 to choose the statement that gives the location of the global maximum and global minimum of f on the interval.

(a) 4 ≤ x ≤ 12

(b) 11 ≤ x ≤ 16

(c) 4 ≤ x ≤ 9

(d) 8 ≤ x ≤ 18(I) Maximum at right endpoint, minimum at left endpoint.(II) Maximum at right endpoint, minimum at critical point.(III) Maximum at left endpoint, minimum at right endpoint.(IV) Maximum at left endpoint, minimum at critical point.
