Answer:
The functions have the same end behavior.
Step-by-step explanation:
Upon a first glace, one relationship I can see between the two functions is their end behavior. For both functions:
as x ⇒ -∞ , f(x) ⇒ -∞
as x ⇒ ∞ , f(x) ⇒ ∞
this is because anytime a function's largest exponent is odd, it will have the same end behavior as a linear function, and anytime the exponent is even, it will have the same end behavior as a quadratic function.
Other than that, the functions may have similar x-intercepts, but I do not believe that is the case. They definitely have different y-intercepts.
