# Interesting Graphs!!!

Module by: Pradnya Bhawalkar, Kim Johnston. E-mail the authors

Summary: Graphing graphs that are rational functions, but are a bit different

Although it is always useful to calculate all the good stuff - domain, vertical asymptotes, horizontal asymptotes, slant asymptotes, holes, x- and y-intercepts, there are some graphs that are just different. This lesson is to show you some unique, yet useful graphs. Try graphing them first on the paper provided and then check your answers. The best way to find the pattern that these graphs follow is to plug in points.

Use graph paper.

y=|x|x y x x

## Exercise 2

y=|x2|x2 y x 2 x 2

## Exercise 3

y=|x+3|x+3 y x 3 x 3

y=|x+2|x y x 2 x

y=xx2 y x x 2

## Exercise 6

y=xx2+2 y x x 2 2

## Exercise 7

y=-6x4x2+5 y -6 x 4 x 2 5

## Exercise 8

y=2xx2+5 y 2 x x 2 5

#### Definition of a lens

##### Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

##### What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

##### Who can create a lens?

Any individual member, a community, or a respected organization.

##### What are tags?

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.
