How do I find the period, amplitude, and frequency from a graph? It doesn't give me any numbers except that the voltage scale is 0.200 volts/division and the time scale is 0.50 milliseconds/division. How do I use these numbers to find the period, amplitude, and frequency?

If it's like using an oscilloscope, then you have to count how many divisions are in a single period, and with that you can calculte the freq. as well

For the amplitude count how many divisions in the y axis does the waveform have
