    I can't decide which graphing calculator to get.

    These are the options and link to specs:

    TI-Nspire CX CAS


    Casio FX-CG20 Advanced Graphic Calculator


    TI‑84 Plus CE Graphing Calculator


    HP Prime Graphing Calculator


    Can someone give me advice or help me decide which to get?

    Just buy one that adds up and does fractions. Graph calculators are great toys but not very useful in anything practical. By the time your have typed in your formula, you could have drawn it out and chances are an exam question would have you work out and plot the points anyway.

    My digital signals lecturer had a brilliant philosophy or drawing graphs. Draw a point at x<0, one at x=0 and one at x>0 and you pretty much have your curve sorted.
