Yankee Posted January 25, 2008 Report Share Posted January 25, 2008 Ok, I am having a long day. I have a deadline of 9:00 am tomarrow, western time to be able to get this and other stuff done. Please help. I will give you 2 Reps if you do! Thanks Fine the domain and range of each function:{(2,7)(4,9)(2,11)(7,13)(5,9)} Also need to find the domai and range for this:{(1/2,1)(-1,2/3)(0,3)(-1/4,2/5)(1/2,0)} Thanks for helping if you do! I will also be adding more, thus, adding more reps and stuff, I just need this done by 9:00 AM >.< Link to comment Share on other sites More sharing options...
JerryFreelance Posted January 25, 2008 Report Share Posted January 25, 2008 What do you need? The equation and then the domain/range of that equation? Or just D/R of those values? If just values, then for the first one: Domain: 2 < x < 7Range: 7 < y < 13 Second: Domain: -1 < x < 1/2Range: 0 < y < 3 Link to comment Share on other sites More sharing options...
RickiMinaj Posted January 25, 2008 Report Share Posted January 25, 2008 So thats what u meenin that caseBhims got it 100%umm though u might want to recheck the second problem bhim Link to comment Share on other sites More sharing options...
JerryFreelance Posted January 25, 2008 Report Share Posted January 25, 2008 Why? What's wrong with the second problem? EDIT: Oh wait, I see it... Max domain is .5 xP thanks gphaku Link to comment Share on other sites More sharing options...
RickiMinaj Posted January 25, 2008 Report Share Posted January 25, 2008 the firstwouldnt it be 13-2cause 13 is the biggest number Link to comment Share on other sites More sharing options...
JerryFreelance Posted January 25, 2008 Report Share Posted January 25, 2008 What? I didn't say 13-2?? Link to comment Share on other sites More sharing options...
Yankee Posted January 25, 2008 Author Report Share Posted January 25, 2008 Ok, thanks, I got it, I will give you 2 rep in a sec, I got more, lol Find the range of the function rule y = 3x + 48. {0,5,7,11} 9.{2,0,0.25,1} Those re 2 seperate problems, it would be much apriciated if any of you can help with these to ^_^ Link to comment Share on other sites More sharing options...
RickiMinaj Posted January 25, 2008 Report Share Posted January 25, 2008 What? I didn't say 13-2??Woops i was looking at ur domain and got it confused with ur range Link to comment Share on other sites More sharing options...

Dark Supreme Posted January 25, 2008 Report Share Posted January 25, 2008 Find the range of the function rule y = 3x + 48. {0' date='5,7,11} 9.{2,0,0.25,1} [/quote']I took this about a year ago. Ill do it as Y is the Domain. (Our school usually states if y=domain or range) ( i am not considering the Absisca or Ordinate since this is not a Co plane). 8.{-4/3, 1/3, 1, 7/3} 9.{-2/3, -4/3, -4.25/3, -1} Link to comment Share on other sites More sharing options...

Yankee Posted January 25, 2008 Author Report Share Posted January 25, 2008 Yes, here they are: There are 3 questions here, that is why there will be 1. 2. and 3.Write an equation in pint-slope form for the line with the givin slope through the givin point:1. m = -3;(2,1) 2 m = -1/2;(2,-4) 3. m = 2;(3,-1) Link to comment Share on other sites More sharing options...
Yankee Posted January 27, 2008 Author Report Share Posted January 27, 2008 Here are the last things I need help with, PLEASE HELP! Write an equation in point-slope form for the line with the givn sloe and through the givin pont:1. m = -1/2;(2,-4) 2. m = 2;(3,-1) Find the sope of the line passing through each pair of points:1. (-2,-1),(3,4) 2. (-3,1),(2,-2) 3. (4,3),(-2,5)Write an equation in slop-intercept form for the line through the givin points (1,4);(2,7) Write an equation in slop-intercept form for a line that is parallel to the givin line and passes through the givin point: y = -1/4x + 9;(-4,4) Write an equation in slop-intercept form for a line that is perpendicular to the givin line and passes through the givin point:y = 1/3x + 5;(0,-5) Link to comment Share on other sites More sharing options...
