We use functions in our daily life though we may not have recognized them as such. write two functions, one of which must be a composite function.  Describe what information you want to learn by applying the functions (the reason you will write those functions). Explain what each of the functions does. Describe what item or characteristic is represented by each of the variables used in the functions. The starting function must have three or more variables and at least two different operators. The second function must use the first function as one of its arguments and must use two or more other arguments.
