  1. Describe what a function does in your own words
    It takes input or mathematical data and produces a result or output through mathematical computations.
  2. Calculate the output of the following function
    f(x) = {

x^2 if x is even

x+10 if x is odd

}

If the input is an even number the result will be that number to the 2nd potency
If the input is an odd number the result will be that number plus a value of 10.

  1. What will be the output for the following inputs?
    • a) f(2) = 4
    • b) f(7) = 17
    • c) f(0) = 0 (if zero taken as an even number); 17 (if zero taken as an odd number)
  2. 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 is a computation or mathematical process that takes an input data, compute it and gives 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

f(2)=2x2=4

  • b) f(7) => 17

f(7)=7+10=17

  • c) f(0) => 0

f(0)=0

  1. Describe what a function does in your own words
    Function gives you an output which depends on your input. It`s a mathematical formula.

  2. Calculate the output of the following function

f(2) = 2^2 = 4
f(7) = 7+10 = 17
f(0) = 0^2 = 0 (i had to google if 0 is an even or odd number :))
