Based on its degree, what kind of polynomial is this?<br> h(x)=4x^4+2x-5
MissTica
To estimate the degree of a polynomial, you just have to take a look at the highest power in the expression. Since here, that is number 4, then it means that this polynomial is a fourth degree polynomial, or quartic polynomial, if you want to sound smart. :)
