The first two look like normal polynomials to me.

For polynomials,

if the highest power is even then the ends will both be above or both be below the x axis.

if the highest power is odd then one end will be above the x axis and one below.    (both heading off to + or - infinity)


The last one looks like it could be a part of a Sideways parabola.


Now you tell me which is which.   And you tell me why you think so. 




Please no one answer over me.
