1)A function is a computation which takes an input and callculates it into an output.
It consists of a function-name and an input(functionname+input=syntax) which generates the
output.

Describe what a function does in your own words:

A function performs a computation based on an input number and returns an output number. It has the form f(x) and computes the output based on the expression or algorithm e.g. x+1; x^2; x+10.

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?

  1. f(2) = 2^2 –>4
  2. f(7) = 7+10 ->17
  3. f(0) = 0^2 ->0

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

}

f(x) = x/4-5 (shorthand)
