  1. Describe what a function does in your own words
    A function takes an input and processes it and give you back an output. It conceals the logic from users. You don’t need to know the inner workings of a function to take advantage of it.

  2. Write the definition of a function f that takes an input x, divides it by four and then outputs that result subtracted by 5.
    f(x) {
    return (x / 4) - 5
    }
