8-17.

Which of the following equations are polynomial functions? For each one that is not, justify why not. Homework Help ✎

*y*= 3*x*^{2}+ 2*x*^{2}+*x**y*= (*x*− 1)^{2}(*x*− 2)^{2}*y*=*x*^{2}+ 2^{x}*y*= 3*x*− 1*y*= (*x*− 2)^{2}− 1*y*^{2}= (*x*− 2)^{2}− 1*y*=*y*=*x*+*y*=*x**y*= −7

The equations in (c), (f), and (g) are not polynomials. Refer to the Math Notes box for this lesson if you are confused.
