Definition
The term "input" refers to the value you put into a function or relation. It’s the variable or number that you provide to see how it affects the output.
For example, if you have a function f(x) = 2x + 3, the input is the value of x that you substitute into the function. If you input x = 4, then the output would be f(4) = 2(4) + 3 = 11. So, in essence, the input is the starting value that you use to calculate the result.
