Mama's Little Function

Got a baby function
Named f(x)
He takes a '2' and adds 3x.
Give him a two, now the answer's GREAT:
f(2), (y!), it equals 8!

Chorus:
Mama's little function eats xs, xs
Mama's little function yields f(x) (twice)

An x is in the oven,
Shut 'im in tight
(Quench my algebra appetite!)
When he finish cook'n
Whatcha got there?
Shut my mouth! An ordered pair!

Chorus

Bring out the functions!
(Get out the lead!)
Gotta get these functions fed.
Whatcha gonna feed it?
Nothin else to choose
xs are what these functions use!

Chorus

Functions gobbled xs
From the domain
(Listen close to this refrain)
The xs it gobbled - 
WOW - what a change!
It spit out ys to make the range!

Chorus

Cram it with xs
Grind out the ys
(You're in for quite a big surprise!)
Look at 'em closely...
Put on your specs
Whaddaya know - y! (It's f(x)!)

Chorus

Give f a function (g!)
(not an x) instead;
Function f will be well-fed!
The resulting composition
A wonder to see
A brand new function called f of g!
