i have never used a graph calculator before in my life, first time touching it. i prefer the hand method right now for precal, but i want to be able to confirm my answers. i have a ti-83, i imagine its old, been sitting around for a while....should i upgrade?
ok the problem i need to graph is -log3x+2
a step by step guide would be appreciated, i attempted but it just said error.
thanks guys! i would spend time with tutorials but i have an exam tomorrow.
