  1. Describe what a function does in your own words

A function is a block of code that performs a task. It can return a value or not. It is called in blockchain as smart contracts. When it returns a value the coder decides the type. That can be a string, a character, an integer or a number.

  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.

f(x) (x/4)-5

Describe what a function does in your own words

A function is a program where an user gives and input to get a result (output) obtained through the language written inside the function

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 is even  f(x)= x^2  f(2)= 2^2=4
b) f(7)  7 is odd  f(x)=x+10  f(7)=7+10=17
c) f(0)  0 is even  f(x)= x^2  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

0 is an even number so the result is defined :wink:

A function is a mathematical calculation which involves an input that produces a logical output as a result of the function’s computation.

a.
When x = 2, the function will be f(x) = {
x^2
}
:arrow_right: making the answer 4

b.
When x = 7, the function will be f(x) = {
x+10
}
:arrow_right: making the answer 17

c.
When x = 0, the function will be f(x) = {
x^2
}
:arrow_right: making the answer 0 (or maybe there will be some sort of error saying tht 0 is an undefined input or something idk :sweat_smile:)

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