In this question, we want to find the net change in the value of the function between the given inputs.
00:06
Here i have f of x, which is equal to 3x minus 2, and i'm on the x interval from 1 to 5.
00:14
Now, if i want the net change in the value of the function, that means i'm looking for the final y value minus the initial y value.
00:26
So i'm trying to find the final y value.
00:30
And from this, i subtract the initial y value.
00:39
So my final y value, that is occurring when x is equal to 5.
00:45
So my final y value, that is f of 5.
00:52
From this, i'm going to subtract my initial y value.
00:57
My initial y value is the y value when x is equal to 1.
01:03
So final y value minus initial y value gives you f of 5 minus f of 1...
