Question 152354
All of your answers look good except for the first problem, part e.
Given: {{{52y^4+7x+2}}} ...You said "This is not a polynomial"  Why is it not?
It certainly qualifies as a polynomial (a trinomial in this case) because there are no terms with  variables in the denominator and no terms with variables under a radical sign.
This polynomial is of degree 4 because of the {{{52y^4}}}
