    Calculating (f of g)(3): Find the Solution

    I'm just not seeing what you are saying for some reason, if (x)=3 don't I substitute every (x) with 3?

    You are absolutely correct, sorry, I see now that I put it in improperly. I've made it harder^2

    I see. Thanks again, I knew it had to be a simple solution but it eluded me for days.

    Calculators Ridiculously simple TI89 question

    YEAH! That did it! Thank you so much. Now, how did I do that in the first place? Does the variable get set to a default when you define it in an equation? Just curious. You just made my whole semester, thank you so much!

    Calculators Ridiculously simple TI89 question

    This is just driving me crazy, I know its a simple mode adjustment but I just can't find it. I am trying to display answers in algebraic notation but keep getting numbers that I can't even determine to base of. Example: 3x^2(-5) yeilds -540 when I am looking for -15x^2. If anyone could...
