I'm in electronics for a living and a life. Math is the key to all things in our existence. Still I hate the practice. Much props to Coaster for his skills in the subject. No wonder he needs so much drugs. Even with them I have trouble applying myself strict enough to accomplish the mathematical feats I desire to master. Otherwise I may could be the next Einstein but I cannot because I am me and who I am.

I give Coaster his props though. A drugged up mathemetition. :thumbup:  Gotta have quite a view.

yeah answer is right unless the formula you gave us is wrong.

if you meant for the whole exponent to be x+1 you need to put it in  ( ) like this: 5-2^(x+1) then the answer would be...

Range: [5,-infinity)

make sure to use those ( ) they are key. especially with a graphing calculator like the ti-83.

common mistake though. keep up the good work :thumbup:
