(10 points) help plz

Answer 1

Answer:

(c) No; There is an exponent on a variable x that is not a whole number

Step-by-step explanation:

Given

$f(x) = x^2 - \sqrt[5]{x}$

Required

Determine if the function is a polynomial function of not

A polynomial function is represented as:

$f(x) =ax^n + bx^{n-1} + cx^{n-2}+........+z$

Where n is an integer and the least power is 0

So, we have:

$f(x) = x^2 - \sqrt[5]{x}$

The degree of x is $\frac{1}{5}$ ----- i.e. not an integer

Hence, the function is not a polynomial
