Function is a mathematical method which is ‘does’ stuffs depend on it’s returning type. For example, a ‘plus’ function would return with the addition of 2 parameters from the input to the output.
a, f(2) = 4
b, f(7) = 17
c, f(0) is a tricky one. If we consider 0 as an even, then the answer is 0, but if we consider 0 as an odd number then it’s 10. maybe we throw exception for 0.
function f ( x ) {
return (x / 4) - 5;
}
0 is an even number, so f(0)= 0
You are right, but sometimes 0 is exceptional and have to handle carefully. For example, if you write a function with input x and you want to divide 10 by x, you cannot do 10 / x if x = 0. That was my initial thought but yeah, maybe I confused myself too much :D.
Homework on Functions - Questions
Describe what a function does in your own words.
Function is like an expression, computation or relation from a set of inputs and a set of outputs. Each input is related with excatly one output.

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
2a. 4
b. 17
c. 0
