What are the domain and range of the function?
(E R is the weird E and R sign, I believe it means infinite)
y = 2x + 5
Domain X  X E R ; Range y  y >= 0 < My answer
Domain X  X E R ; Range y  y E R
Domain X  X E R ; Range y  y > 2.5
Domain X  X E R ; Range y  y >= 5

Best ResponseYou've already chosen the best response.1just to clarify: symbols are: \[e~ is \in \] and R is the capital R which looks like 2 R's drawn over the top of eachother?

Best ResponseYou've already chosen the best response.0yes and I chose A cause I didn't see anything negative in the equation, I could be very wrong though, I tried drawing it out on a graph but I Just can't see it

Best ResponseYou've already chosen the best response.0ok so almost the same thing, https://k12va.aplusanywhere.com/R85Content/media/pictures/algebra1a/42214.gif?ts=1433574583941 I know this is an easy one but I want to be certain I get it right lol A: https://k12va.aplusanywhere.com/R85Statics/media/pictures/algebra%20ia/4.2.2/test/14/1419027972933/1366x768/1419027972933.png B: https://k12va.aplusanywhere.com/R85Statics/media/pictures/algebra%20ia/4.2.2/test/14/1419027972929/1366x768/1419027972929.png C: https://k12va.aplusanywhere.com/R85Statics/media/pictures/algebra%20ia/4.2.2/test/14/1419027972931/1366x768/1419027972931.png D: https://k12va.aplusanywhere.com/R85Statics/media/pictures/algebra%20ia/4.2.2/test/14/1419027972927/1366x768/1419027972927.png

Best ResponseYou've already chosen the best response.1cool... so domain are all possible inputs (x values) and range is all possible outputs... yeah? just based on where ur graph starts and stops i'd put domain as 04 and range as 0 to 2... i don't really see any of the answers as correct as i can't see the equation for the line, so i don't know if it continues on past x=4...? otherwise it looks like it may curve back downwards towards the x axis

Best ResponseYou've already chosen the best response.0yea that's what got me xD cause I mean there is no stop point on the graph so I was like uuuugh xD

Best ResponseYou've already chosen the best response.1given the choices we have though... wouldn't D be a better answer than C tho?

Best ResponseYou've already chosen the best response.0The second statement is the correct :domain X and range Y is all elements E(numbers) of real numbers R for this function exist because the function is a straight line
