why arent 1 and 3 polynomals?

[hasty oyster]

In polynomials , degrees of all variables should be whole numbers . Since degree of x in 7/x is -1 in option 1 and all of the degrees of x in option 3 are integers and not whole numbers , they aren’t polynomials .

Oh

Arent whole numbers because if exponenciated by negative they are fractions

Ok

Thank you very much
