# How to Graph an Equation / Function – Excel & Google Sheets

*This tutorial will demonstrate how to graph a Function in Excel & Google Sheets.*

**How to Graph an Equation / Function in Excel**

**Set up your Table**

- Create the Function that you want to graph
- Under the X Column, create a range. In this example, we’re range from -5 to 5

**Fill in Y Column**

Create a formula using the Function, substituting x with what is in Column B.

After using this formula for all the rows, you should have a table that looks like below.

### Creating Scatterplot

- Highlight Dataset
- Select
**Insert** - Select
**Scatterplot** - Select
**Scatter with Smooth Lines**

This will create a graph that should look similar to below.

**Add Equation Formula to Graph**

- Click Graph
- Select
**Chart Design** - Click
**Add Chart Element** - Click
**Trendline** - Select
**More Trendline Options**

6. Select **Polynomial**

7. Check **Display Equation on Chart**

**Final Scatterplot with Equation**

Your final equation on the graph should match the function that you began with.

**How to Graph an Equation / Function in Google Sheets**

**Creating a Scatterplot**

- Using the same table that we made as explained above, highlight the table
- Click
**Insert** - Select
**Chart**

4. Click on the dropdown under Chart Type

5. Select **Line Chart**

**Adding Equation**

- Click on
**Customize** - Select
**Series**

3. Check **Trendline**

4. Under Type, Select **Polynomial**

5. Under Label, Select **Use Equation**

**Final Scatterplot with Equation**

As you can see, similar to the exercise in Excel, the equation matches the function that we began with.
