  1. Describe what a function does in your own words
    A function is a mathematical computation such that given an input, it yields the computed 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) = 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.
f(x) = (x/4)-5 = (x-20)/4

A function defines an interaction of input given f(x) syntax, which then gives the output given x and f(x).

f(x) = { x^2 if x is even x+10 if x is odd }

f(2)=2^2=4

f(7)=7+10=17

f(0)=0^2=0

f(x) = {(x/4)-5}

1 - Describe what a function does in your own words

A function is a calculation allowing to associate a variable called “number” with x which has repercussions on the result.

2 - Calculate the output of the following function

f (x) = {

x ^ 2 if x is even

x + 10 if x is odd

}
3 - What will be the output for the following inputs?

a) f (2) = f (x) = 2 ^ 2 = 4
b) f (7) = f (x) = 7 +10 = 14
c) f (0) = f (x) = 0

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