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:
$$\left(x + 1\right) \log{\left(0.5 \right)} = \left(1 - x\right) \log{\left(0.5 \right)}$$
- No
$$\left(x + 1\right) \log{\left(0.5 \right)} = - \left(1 - x\right) \log{\left(0.5 \right)}$$
- No
so, the function
not is
neither even, nor odd
