Anytime you're given a problem that tells you the point, so this is basically saying that when x is 5, the y coordinate is 14.
00:14
So when i get two points of form, y minus the y coordinate equals the slope x minus the x coordinate, i already know that this would be x1 and this would be y1, which brings me to my next point that when i see f prime of 5 is equal to 5 .6.
00:33
That number is my slope.
00:37
So the linearization is basically set up this way, y minus 14 is equal to 5 .6, and then x minus the x coordinate.
00:48
I guess i should have underlined that to a 5.
00:51
But they want you to write it as f of x.
00:54
So i'm going to go ahead and distribute this 5 .6 into the problem.
01:00
Let's see, 5 .6 times 5 is 28.
01:05
But then i need to add 14 over...
