## Mapping Formula

**(x+h) , (ay-k)**

Here, you plug in your h, k and a values.

**For example: **

y= -0.5(x+3)^2 + 3

This equation will turn into:

(x - 3) , (-0.5y+3)

*Remember that h will have the opposite sign*

## How Do I Turn My Equation into a Chart?

After plugging the equation into the mapping formula, you can make your chart. But in order to do this, you must use the basic quadratic function! (Also known as y=x^2). One chart will be the basic quadratic equation while the other chart can be the chart of your equation.

After doing so, plug in the mapping formula points into the basic parabola chart and solve it. The outcome will be your new chart to graph! Visual steps are provided below.
