Describe what a function does in your own words

Function is form of a math computation where there is an input and it solves to give an output

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

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

  1. Describe what a function does in your own words
    A function gets input parameters and performs an action with these parameters (calculation / string manipulation / validation checks /…) and returns a result.

  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) --> 4
  • b) f(7) --> 17
  • c) f(0) --> 0
