Reflecting a function about y=0

[libman]

Is there a way to reflect a function about a line other than y=x. I want to reflect a function about the x axis.

Thanks

Hello libman,

One way to create this reflection is to use function definitions. Click Function Definitions on the toolbar and enter f(x) = xsinx for example. Click OK.

Plot y = f(x) and then y = -f(x). This will give you the original equation and its reflection.

Another way to demonstrate the reflection is to create a dataset from your function. This dataset can then be reflected. Select the function, right-click and choose Create Data Set. Click OK. Select the dataset and the line that you would like to reflect it in. Right-click and choose Reflection.

Hope that helps,

Simon

Thanks Simon,

I know I could multiply the original function by -1. I was wondering if there was a built in function for getting reflections.

The data set technique works great! Thanks!  

Nice if I could select an graph and then the line, etc about which I want to do the reflection and right click and choose reflection.

Thanks,
Libman
