Homework on Functions - Questions

  1. Describe what a function does in your own words

A function is a computation with a variable input required to generate the output.

  1. Calculate the output of the following function
f(x) = {

x^2 if x is even

x+10 if x is odd

}

What will be the output for the following inputs?

  • a) f(2)
    f(2) = 2^2 = 4

  • b) f(7)
    f(7) = 7+10 = 17

  • c) f(0)
    f(0) = 0

  1. 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) = x/4 -5
