Question

Is the function f(x)=5x^2-3x^4 + 3/4x-7 a polynomial function?

Answer 1

Not a polynomial

Explanation:

`f(x)=5x^2-3x^4 +(3)/(4x)-7`

A polynomial function does not have x in the denominator

If there is any radical in f(x) , then it is not a polynomial

If there is any x in the denominator in f(x), then it is not a polynomial

In our given f(x), we have x in the denominator of third term

So the given f(x) is not a polynomial.
