Answer:
There are Even, Odd and None of them and this does not depend on the degree but on the relation. An Even function: 
And Odd one: 
Step-by-step explanation:
1) Firstly let's remember the definition of Even and Odd function.
An Even function satisfies this relation:
An Odd function satisfies that:
2) <u>Since no function has been given</u>. let's choose some nonlinear functions and test with respect to their degree:
3) Then these functions are respectively even and odd, because they passed on the test for even and odd functions namely, and 
for odd functions.
Since we need to have symmetry to y axis to Even functions, and Symmetry to Odd functions, and moreover, there are cases of not even or odd functions we must test each one case by case.

========================================
Explanation:
If x repeats itself, then we don't have a function. For instance, relation 2 has the x value -4 show up twice. That input leads to multiple outputs which is why we don't have a function. Relation 4 is a similar story (this time the input 'u' shows up twice).
Relations 1 and 3 don't have this issue, so they are functions.

Answer:
I got 37.5 as my answer
Step-by-step explanation:
create your proportions by making the fractions 16/20=30/x (you can use this shortcut because the lines are parallel)
then cross multiply to get 16x=600
divide by 16 and x=37.5
