Okay, in this problem, we're supposed to classify this function as either a polynomial, a rational function, or a root function.
00:12
Okay, so let's just copy it down first.
00:14
We have f of x equals, what is it? let me look at it.
00:18
3x squared minus c.
00:21
3x squared minus c.
00:24
All right, well, let's think about what kinds of functions these are.
00:26
Let's think about a rational function first.
00:29
A rational function, we can look at the word rational.
00:33
And look at its root word ratio to determine what kind of function this is.
00:37
This is a function that has a fraction.
00:40
This is a function that has maybe some function, maybe like x plus two, and then maybe over to x squared.
00:47
Notice what do we have here? first of all, we have a fraction, and then second of all, we have a variable in our denominator...
