the range is all the values that y takes on
so y do u think its wrong
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)
Yeah you have the right answer

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 
I just dont get how you solve for x since it is an exponent

thank you for that, that actually cleared it up. I know what the definition of range is and have used it before. I just didnt know how to mathematically solve the equation

At least I am trying. I could be like some students and just completely wing it. I am fairly knowledgable in the other areas and it is multiple choice so I should at least pass

Im not sure, probably wont get my actual grade back until next week. I copied at least 4-5 answers out of 25 off the kid sitting next to me and he isnt even that smart.
Now I am locked out of my own fucking room for the next 3 1/2 hours, stuck at the library cruising the internet and about to work on some homework
and my "friend" who said he'd smoke with me, made up some lame excuse as to why he couldnt now
my day has fuckin sucked

i hate those guys...
I hate them too. But hes a bitch and bitches get what bitches get. If you were a little bitch I would do the same thing to you
Thats the same kid who made an excuse to not smoke me out, after I helped him with math several times. He has never done me a favor
Last time this kid sold my friend 10mg vikes but when he showed up, and we googled them, they were 5mg. So he has coming what he has coming.

I'd be pretty pissed off if you helped me :P
actually we take our tests in groups of 4 from class and all help eachother. it was my idea
I have gotten B's on both exams so far. Im doing pretty well in the class

I cant believe I got a fucking 78 on that exam. I seriously was expecting a 70 at best but more around a 65 realistically.
Time for a shower, smoke, and a cup of coffee. Then I think ima drag my ass up to McDonalds for some breakfast!
