Answer 1

\[f(x) = \sqrt[4]{x^5} - x ^{2} + 3\]

Answer 2

@jim_thompson5910 can you help please?

Answer 3

the exponents must be integer in a polinomial function

Answer 4

julian25 is correct

Answer 5

the first term can be rewritten into x^5/4, but that's not an integer exponent

so this is NOT a polynomial function

Answer 6

okay so than what?

Answer 7

that's it, the question is answered

Answer 8

Sorry didnt mean to write that.. How do you know if it is a polynomial function

Answer 9

if all the exponents over the variables are integers, then the function is a polynomial function

Answer 10

okay i got it
