A lot people get a little freaked when I start talking about functions.
Especially if they know I’m a math mom. But today you’ll see a way to look at functions that will make you smile!
What is a function?
You might have seen this:
But that’s not a function, that’s just the way snotty-potty mathematicians like to write a function.
Of course, to be fair, there’s lots of functionality in writing it that way – pardon the pun. But we won’t go there. You have to be happy with functions before you care how they’re written.
And that’s what this is all about. Getting happy with functions.
Ahem… So what IS a function?
A function has three parts:
But there’s a big hairy stipulation.
If you use the inputs and follow the instructions and I use the same inputs and follow the exact instructions… then we must get the same thing!
I know – it sounds reasonable, right?
Consider shortbread cookies – my favorite. I need 1.5 cups sugar, 4.5 cups flour and a pound of butter. These are the inputs.
When I follow the instructions correctly (as written by my Ma in my super special cookbook), I get the output of perfect and super yummy shortbread cookies!
If you were to use those same ingredients (inputs) and Ma’s recipe (instructions), you would get the exact same amazing cookies (outputs).
So now that you know what a function is, where can you see them?
P.S. Mix ingredients, roll into a log and chill. Slice discs 1/4 to 1/2 inch thick from the log and bake at 325° for 20 minutes.
