I have searched all over the internet, but can not find an explanation as to how the curve is made. I am studying RLC circuits and trying to determine Q factor. Is their an equation for the curve?

Yes, you write the transfer function for the circuit. and then plot the input vs. output of that function over the frequency range of interest.

 

What is the transfer function?

 

What is the transfer function?

It's the output response of the circuit divided by the input signal.
