This problem wants us to find from the graph of a function g that were shown, the average rate of change from the x value 0 to x value of 3, and simplify our answer as much as possible.
00:10
To be able to find the average rate of change, what we need is the evaluation for whatever our intervals are.
00:17
So let's say our interval was a to b.
00:19
We would need the evaluation of b minus the evaluation of a divided by the difference of our two input values, b minus a.
00:28
So in this case, we're asked to find the average rate of change from zero to three.
00:33
So we need to find f of 3, subtract f of 0, and then divide that by 3 minus 0.
00:40
So looking at our graph, it looks like our point of 0 for x maps to 1 for the y value, so 01.
00:48
And then the x value of 3 matches to the y value of 8, so 38 is our other point...
