2.5 Applying the Power Rule

In short

This topic focuses on recognizing opportunities to apply derivative rules to simplify differentiation, specifically introducing the power rule. You are expected to calculate the derivative for functions of the form f(x) = x^r by directly applying specific rules rather than relying solely on the limit definition of the derivative.

What else do you need to know about Applying the Power Rule?

You should be able to apply these mathematical rules or procedures both with and without technology.

Can you do these?

  • I can use the power rule to calculate the derivative for functions of the form f(x) = x^r.

How is Applying the Power Rule tested on the exam?

On the AP Exam, you must present clear mathematical structures that connect your work with definitions or theorems. Dropping important notation or failing to present proper structure will cost you points, even if they arrive at a correct numerical answer. When evaluating mathematical expressions on a calculator, you must use specified rounding procedures, typically rounding or truncating to three places after the decimal point. It is highly recommended to store intermediate calculations in the calculator to avoid the accumulation of rounding errors.
