Answer:
See below.
Explanation:
I notice that one graph has both positive and negative points (the first) which the other (second) only has positive values. We can also see a difference in the two polynomials: the first has two places where x is raised to an odd power: x^3 and x^1 (or x). If x were negative, these would both result in a negative value. The second equation only has exponents that are even. Negative values of x would result in a positive value: e.g.,(-3)^2 = 9 and (-4)^4 = 256.
I wonder if the curve shapes will always follow the rule of an odd exponent in that expression will produce the same shape of curve.
