Softsign Function (Graph)
Calculate and graph the Softsign Function and the table of its first derivative.
The Softsign function is used in applications such as activation functions for neural networks.
| \( \normalsize Softsign\ function\ \phi (x)\\ \normalsize \phi (x) = \large \frac{x}{1+|x|} \\ \normalsize \phi ' (x) = \large \frac{1}{(1+|x|)^2} \\ \) |
