Determine if the function is a power function. If it is, then state the power and constant of variation.
-$$\mathrm { C } = 2 \pi \mathrm { r }$$
A) Not a power function
B) Power is 1; constant of variation is $2 \pi$
C) Power is 0 ; constant of variation is $2 \pi$
D) Power is 2; constant of variation is $\pi$

Question

Quizplus · Accepted Answer

The given function $C = 2 \pi r$ is a power function because it can be expressed in the form $C = k \cdot r^n$, where $k = 2 \pi$ is the constant of variation and $n = 1$ is the power.
