# Using the calculator to graph

### Exponential Functions w/ Translations!

## Vertical Translation Example:

## First STEP

- Find the Y =
- Clear out an data in Y1, Y2, Y3, etc.

<<<<<<<<------------------------------------------------------------

**This what your screen should look like before you begin!**

## Where y = is located on the calculator!

## Second Step

Let's insert the following equations into y = so they are on the same graph:

- y = x^2
- Y1
**(arrow down)**

- y = x^2 + 2
- Y2
**(arrow down)**

- y = x^2 - 2
- Y3
**GRAPH**

## Does your graph match the graph below?

## Horizontal Translation Example:

## First Step

- Find the Y =
- Clear out an data in Y1, Y2, Y3, etc.

This what your screen should look like before you begin!

## Second Step

Let's insert the following equations into y = so they are on the same graph:

- y = 2^(x + 5)
**(arrow down)**- Y1

- y = 2^x
**(arrow down)**- Y2

- y = 2^(x -.5)
- Y3

- GRAPH

## Does your graph match the graph below?

## Don't forget!!!

Horizontal Translation:

You move in the opposite direction of the what sign is in the equation

+ = move left - = move right
