We are given f of x in this problem is 2x plus 7.
00:07
And the very first thing that they want you to do for, well, i'll just put number one, is figure out what f of x plus h is.
00:15
That's your four -step process.
00:17
So what you're doing is replacing the x in the problem with x plus h.
00:22
So you can see i just rewrote f of x, but i took out the x.
00:25
I need to replace it with x plus h.
00:28
So as i distribute this in here, i have 2x plus 2h plus 7.
00:36
All right, good.
00:38
So now the second step is to figure out f of x plus h minus f of x.
00:46
So what i need to do is take what i just found, the 2x plus 2h plus 7.
00:54
I need to subtract off the original problem of 2x plus 7...
