Cracking The Ap Calculus ab Exam 2018

Notice that this one doesn’t cancel as conveniently as the other problems did. In order to simplify this

expression, we have to multiply both the top and the bottom of the expression by (the

conjugate of the numerator).

Simplify.

The derivative is .

PRACTICE PROBLEM SET 3

Now find the derivative of the following expressions. The answers are in Chapter 19.

1.f (x) =   5x  at  x   =   3

2.f (x) =   4x  at  x   =   −8

3.f (x) =   5x^2    at  x   =   −1

4.f (x) =   8x^2

5.f (x) =   −10x^2

6.f (x) =   20x^2   at  x   =   a

7.f (x) =   2x^3    at  x   =   −3
