Question

Find the maximum and minimum values of the function over the given interval. f(x)= √x; 4 ≤ x ≤ 9

A) minimum: 0; maximum: 1

B) minimum: 2; maximum: 9/2

C) minimum: 4; maximum: 9

D: minimum: 2; maximum: 3

Answer 1

Option C

Explanation:

the function sqrt(x) is always growing, so the minimum and maximum of the expression will be the same of the maximum and minimum of the interval.
