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:
$$\frac{x}{- x + 1} = - \frac{x}{x + 1}$$
- No
$$\frac{x}{- x + 1} = \frac{x}{x + 1}$$
- No
so, the function
not is
neither even, nor odd
So, check:
$$\frac{x}{- x + 1} = - \frac{x}{x + 1}$$
- No
$$\frac{x}{- x + 1} = \frac{x}{x + 1}$$
