A function Takes an input “x” and gives you an output

f ( x )  =  {

x^2  if  x  is  even

x+10  if  x  is  odd

f(2) = 4

f(7) = 17

f(0) = 0

  1. Describe what a function does in your own words

A function is a computation. The mathematical formula as refereed to as syntax.
A function uses syntax to represent a calculation, an input and and output. You give something (x) a function, a calculation takes place and you get an 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) 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 is a process in which the input is changed to an output using some kind of mathematical operation. It basically defines the relationship between input variable and output variable.
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) = 2^2 = 4

  1. A function is a thing that takes some arguments, does something with them by executing a step-by-step algorithm, and returns the computed result as an output. Of course, this is a definition of a mathematical function, or a pure function as we say in programming, and a function that is not pure is a little bit complex - it can have side effects, that is, the execution of a function can modify some external state which will then result in changing the behaviour or output of this function or even other functions in the system.
