00:01 In this question, we are asked to find the average rate of change of the function f or the given interval.
00:06 And the general formula is a equals to f of b minus f of a divided by b minus a.
00:15 In our case, a equals to 2 and b equals to 3.
00:20 So we are going to get f of 3 minus 2 divided by 3 minus 2.
00:30 F of 3 equals to 3 squared plus 5 times 3 minus 5.
00:38 And f of 2 equals to 2 squared plus 5 times 2 minus 5 divided by 1...
