My daughter needs a graphing calculator for her math course. If you have one laying around that you are not using, she would be happy to make good use of it!\
Edit: I am very new here, so I don't understand the rules very well. I hope I am not stepping on any toes! I have added an image of a graphing calculator. They haven't changed much since I used one 45 years ago in high school. Although there are very good ones online, my daughter's teacher would like her to use a graphing calculator for tests.
