In this problem you will write a function to implement following math function:

(This is an approximation of an activation function used in machine learning)

The function called "activation" should take an "input" of type double and should provide an "output" of type double. Let us assume that this function will be called by the following process() function, which is in-turn called by main(). (Hint there are two ways of getting the output from the function. You can use any option.

//declare your function "activation" function here. [1 point] 

//define your function "activation" function here. [10 points] void process(){ double dX; double dFx; //call your function "activation" function here. [4 points] printf("f(%0.2lf)=%0.2lf ",dX,dFx); } int main(){ process(); return 0; }
