  1. Describe what a function does in your own words
    Given and input, a function is a set of operation to calculate the output. A computational process from an input to an output.

  2. 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(x)=x^2 if x is even
    f(2)=2x2=4

  • b) f(7) – x+10 if x is odd
    f(7)=7+10=17

  • c) f(0)
    f(0)=2x0=0
    f(0)=7+0=7

  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.
