  1. Describe what a function does in your own words
    • A function receive parameters (inputs), process it or them with instruction, mathematic formulas or other call to subfunctions to generate an output that is returned to the caller. It’s a way to capture the business logic of a specific action so that it can be replicated and automated in smart contract.
  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) => 4
  • b) f(7) => 17
  • c) 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.

  1. Describe what a function does in your own words

A function converts one value into a new value or it can take a value and modify the input values. A function can standalone and has minimal dependencies typically just depends on the underlying programming language constructs.

  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)

4 – 2 is even - 2^2 is 4

  • b) f(7)

17 – 7 is odd - 7+10 is 17

  • c) f(0)

0 = 0 is even - 0^2 is 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.
