If you are not able to afford a TI-83/84 Graphing Calculator, I have found another option for you to practice below. I found a site that lets you download the TI-83 graphing calculator onto laptop, i-pad, or i-phone. The site below is very consistent with laptops (PC's), it acts a little funny with apple products. Downloading it will be great for the short term; long term, you will need to purchase the device.
