Best ResponseYou've already chosen the best response.0dw:1433586811172:dwYah, our x is going all the way right and left. It's going up much faster than it's moving right or left, that might make it a lil confusing. But we WILL cover all the x's.

Best ResponseYou've already chosen the best response.0oh wait no >.< I messed up sorry I get x and y mixed up, so y has to be equal or over 0? so A ?

Best ResponseYou've already chosen the best response.0sorry I said x first XD I always get confused on those but yea I understand how the x (domain) is going out infinite so it had to be the y that is equal to or greater than 0, thank you! One more cool? :D

Best ResponseYou've already chosen the best response.0A train travels at a steady rate of 80 mph. If the train travels for onehalf hour nonstop, what are the domain and range of the distance function during the trip? A: Domain: t = 0.5 ; Range: d(t) = 40 B: Domain: 0 =< t =< 0.5 ; Range: 0 =< d(t) =< 40 C: Domain: t = 0.5 ; Range: d(t) = 80 D: Domain: 0 =< t =< 0.5 ; Range: 0 =< d(t) =< 80

Best ResponseYou've already chosen the best response.2hmm... k so distance over the time of the trip is between 0 and 40 miles..., so I'd lock in range as between 0 and 40 (depending on time) yeah?

Best ResponseYou've already chosen the best response.2ummm... and domain... in this case relates to time (t) so your domain is between 0 and a 1/2 hour... so domain = 0 to 0.5

Best ResponseYou've already chosen the best response.0If we're gonna lock in 0 to 40 our only choice would be B, so B right? lol
