Okay, i have a picture of f here, and i want to find the anti -derivative of f.
00:08
Okay, and we'll just draw one, and then you can pick which one is it in the exercise.
00:15
Okay, so if we're trying to draw the anti -derivative of f, then that means we're looking for the function that f is the derivative of.
00:24
So f is the derivative of some function g.
00:42
So g is the anti -derivative of f.
00:54
Okay, so f is the derivative.
00:56
Okay, so where the derivative is zero right here, that means g has a max or min right here.
01:14
Okay, here, from here to here, the derivative is positive.
01:21
Okay, f is positive here because it's above the x -axis.
01:27
That means g is increasing.
01:32
F is positive, so g is increasing...
