We're in a hot air balloon, going up to fly
+
The table shows our time and height in the sky
+
At one minute we're three meters off the ground
+
At two minutes we're six meters up, staring down
+
At three minutes we're up nine meters high
+
What's the rule that shows our place in the sky
+
If we multiply any input by three
+
We'll get the output, so that's the rule, you see
+
In goes four, out comes twelve
+
In goes five, out comes fifteen, swell
+
In goes six, out comes eighteen
+
The rule is times three, and the view is pristine
+
What's happening between the in and the out
+
We can always find out without any doubt
+
Make an educated guess and test it out
+
Til' you find what the rule is all about
+
I had a function machine, the best one ever seen
+
I put in a nine, and out came a three
+
I put in fifteen, and out came five
+
And twenty-seven went in, and out came nine
+
There's only one thing I want to know at this junction
+
What on earth is my machine's function
+
If you divide any input by three, you'll get the output
+
So that's the rule, you see
+
In goes six, out comes two for sure
+
In goes twelve, and you know out will come four
+
This input-output table has a rule
+
It's divide by three
+
Man, that's pretty cool
+
What's happening between the in and the out
+
We can always find out without any doubt
+
Make an educated guess and test it out
+
Til' you find what the rule is all about
+
When there are two sets of values
+
And they share a mathematical relationship, there's a functions there
+
And we can use our mind, a mathematical tool
+
To describe the relationship called a rule
+
What's happening between the in and the out
+
We can always find out without any doubt
+
Make an educated guess and test it out
+
Til' you find what the rule is all about
+
What's happening between the in and the out
+
We can always find out without any doubt
+
Make an educated guess and test it out
+
Til' you find what the rule is all about
+
