A power function is in the form
f(x) = axn, where a and n are constants.
Is C = 2πr in that form?
Inactive Tutor
C = 2πr does not have a power (exponent)!
It is not a power function. It is a linear function.

What is the difference between saying it is a linear function and saying it is a function to the first power?
C(r) = 2πr = 2πr1
a = 2π
x = r
n = 1

Arturo, just as Aquinas.
Could it be that the first power is the trivial case and is not considered?

Mark,
It could be defined that way, but technically, first power is still a power.

Yes!
But I hope the students are taught more about how to work with equations than about what to call them.

so is a linear function also a power function (to the first power)?? Or do I say it is not a power function and is only a linear function??
