Question

determine weather the function is a polynomial function. If it is state the degree. F(x)= -8x+x -4

Answer 1

First simplify - you have some like terms there that you can combine.

A polynomial is a combination of terms consisting of constants, variables and exponents that are added or subtracted (if there is more than one term), where all the exponents are non-negative. The degree of the polynomial is the degree of the highest-degree term. The degree of each term is the sum of the powers of the variables (so a constant term has degree 0).

So, what do you think - is that a polynomial? And if so, what's the degree?
