Answer:

f(x) = |x| or f(x) = x² etc.

Explanation:

There are several functions that gives positive value for entire interval [-3,-2].

Like the function, y = |x| , where if you put any negative value of x, the resulting output of the value of y is always positive. Therefore, for domain of [-3,-2] the range of the function will be [3,2]

Again, the function y = x², where if you put any negative number as a value of x, the corresponding value of y will be always positive.

Therefore, for domain of [-3,-2] the range of the function will be [9,4] (Answer)
