Question

The function f(x)= 3/x + 7x^2 is a polynomial
true or false?

Answer 1

What do you think?

Answer 2

It is false because of the 3/x correct?

Answer 3

I'd agree with you(: not a polynomial because it has a negative exponent

Answer 4

any variable power that is not a positive integer or zero --> not a poly.

if it has 1/x or 1/x^2, sqrt(x) etc. not a poly
