A function of x means that you get an answer if you plug in a certain value for x.

A is not a function, because it specifies that x=5
B could be a function, but you'd have to rewrite it in a form y = ....
C is a nice function of x. Just swap it: y=x2
D is a circle. You can't rewrite it as a clean function of x.

So I would choose C.

Answer:

Step-by-step explanation:

According to the Linear Factorization Theorem, a polynomial function will have the same number of factors as its degree. We also know that these factors will have the form (x - c) where c is a complex number.

In this problem, and without factoring the polynomial, we observe that the <u>polynomial function is a 5 degree function so we can know that it will have 5 linear factors. </u>
