Consider the following C function.

float f,(float x, int y) {
    float p, s; int i;
    for (s=1,p=1,i=1; i < y; i++) {
         p *= x/i;
         s+=p;
    }
return s;
}

For large values of y, the return value of the function f best approximates

X^y

e^x

$$\ln (1 + x)$$

X^x

In the C language

At most one activation record exists between the current activation record and the activation record for the main

The number of activation records between the current activation record and the activation record of the main depends on the actual function calling sequence.

The visibility of global variables depends on the actual function calling sequence.

Recursion requires the activation record for the recursive function to be saved on a different stack before the recursive fraction can be called.
