Topic: Help w/ Function

Hi!

I am a newbie who is self-teaching calculus.  I am using Graph 4.2.

How can I plot the following function?

y=SQR(x), where X is not equal to 2

Thank you!

Re: Help w/ Function

To plot the square of x for all values except 2, you can use: f(x)=if(x <> 2, sqr(x))
However it will look the same as f(x)=sqr(x)

You can add a 'circle' marker at the point of discontinuity.
