An example of a polynomial function

Question

Which of the following is an example of a polynomial function?

 f(x) = 5x³ + 2x² – 6x + 7

  

h(x) = 750(1.04)^x 

p(x) = log₃(x)²

Answer 1

Hey! To approach this question, you simply need to understand the definition of "polynomial function" (since all of these are functions).

In essence, you're looking for a function that has some combination/expression of terms (variables, constants, and/or both being multiplied) without any negative exponents!

Something to keep in mind - this is one single expression and not a quotient or product of two expressions! Very important.

I hope that helps to narrow things down!
