Even and odd functions
Let's check, whether the function even or odd by using relations f = f(-x) и f = -f(-x).
So, check:

- No
$$11 - \frac{5 x}{12} = - \frac{5 x}{12} - 11$$
- No
so, the function
not is
neither even, nor odd
So, check:
$$11 - \frac{5 x}{12} = \frac{5 x}{12} + 11$$
- No

- No
so, the function
not is
neither even, nor odd
