AP Calculus AB 2019 FRQ

In our longest tutorial yet, we cover all 6 Free Response questions of the 2019 AP Calculus AB exam. Due to the channel hiatus, this video was released later than it should have, so to all of those who have already taken their AP Calculus exams for the year, we apologize. To everyone who has to take this exam sometime in the future, good luck!

CORRECTION:

For #6c, after finding the limit of f(x) as x approaches 2, state that because f is twice differentiable (NOT h), f' is continuous, so the limit of f'(x) as x approaches 2 is equal to f'(2).

From there, you should use L'Hopital's Rule on the limit of h(x) as x approaches 2, and set that equal to the value 4. From there, find f'(2). You should get that f'(2)=-1/3.
