The Lonely Graph

Lyrics and Performance by Vicki Young
Melody: "Heartbreak Hotel"

When I graph a function, the “y” I want to find.

If that “y” is missing, it’s gonna blow my mind!

‘Cause

It’s not a function,

And it’s so lonely.

Its slope is called

UNDEFINED.

This lonely situation – how did it come to be?

It has not one y-intercept – that letter known as “b”.

‘Cause

It’s not a function,

And it’s so lonely.

It’s slope is called

UNDEFINED.

How do we recognize it? Please come and set me free!

The line, it will be vertical if only “x” we see.

‘Cause

It’s not a function

And it’s so lonely.

Its slope is called

UNDEFINED.
