What do you think?
OpenStudy (sharkfinsoup):
It is false because of the 3/x correct?
OpenStudy (sunnnystrong):
I'd agree with you(: not a polynomial because it has a negative exponent
OpenStudy (mww):
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
OpenStudy (sharkfinsoup):
That was correct thanks so much
