5.43. Homework: Creating Functions from Sample Input and Output

In this homework you will be given some input and output and will determine how the function transforms the input into the output. Then you can either generate code using generative AI like Chat GPT or write the code yourself.

Note

If you work in a group of two to three people, only one member of the group should fill in the answers on this page. You will be able to share your answers with the other group members at the bottom of the page.

5.43.1. Function 1

Function1 takes a list of numbers and outputs a number as shown below:

Input                             Output
function1([10, 80, 100])           90.0
function1([70, 50, 90])            80.0
function1([2, 4, 6, 8])            6.0
