A function is a way of describing what happens to an input ... output values. Instead of writing Function = multiply by 3 we can use algebra. Graphically, \(f(x) = x^2\) is the same as the graph ...

One way to do this is to build functions. A function has three general tasks it can perform; it optionally takes an input, does some processing and ... Function Get-Something { Write-Output 'I am in ...
