A function is a mathematical equation used in computation, that uses a variable (input), processes the mathematical equation and renders an output based on the input.
//Not sure if I got this one right, if anyone could let me know what they think

a) 4 BECAUSE if;
x = 2, 2 = even, x = (x^2) the output is 4

b) 17 BECAUSE if;
x = 7, 7 = odd, x = (x+10) the output is 17

c) LET’S TAKE FOR GRANTED 0 IS EVEN (as I’ve always thought it to be); because I’m confused after reading this; https://www.quora.com/Is-zero-even-or-odd

0 BECAUSE if;
x = 0, 0 = even, x = (x^2) the output is 0

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

  1. Describe what a function does in your own words
    A function is the basis of a problem. It tells us where to put the number and by math it spits out a other number and thats how it solves a problem/task.

It is valid! The parity of zero is even.
So 0^2 = 0 (perfectly valid and defined)

#1104

The parity of zero is even, so 0^2=0
