Best ResponseYou've already chosen the best response.1the first one: f(x) = 8.5x, x =0, f(0) =? x =1, f(1) =?

Best ResponseYou've already chosen the best response.1The graph will stop there, at the point x =40, right? hence for the first piece, we have dw:1438830483660:dw

Best ResponseYou've already chosen the best response.0wait i can't graph (40, 34) bc the y axis given only goes up to 16

Best ResponseYou've already chosen the best response.1Ignore it, you need understand the concept before doing something else. Ok? Now, the second part, f(x) = 12.75(x40) , if x =41, f(41) =??

Best ResponseYou've already chosen the best response.1and we take the value of f for x >40, right?, hence take this part dw:1438830862744:dw

Best ResponseYou've already chosen the best response.1ok, now combine the two.

Best ResponseYou've already chosen the best response.1hence your graph is dw:1438831013456:dw

Best ResponseYou've already chosen the best response.1you just relabel the system, instead of 1,2,you put it 5, 10, 15..... dw:1438831239279:dw

Best ResponseYou've already chosen the best response.0yeah it already does it by 2's but im not sure if im supposed to relabel it but if i don't how would i show the restrictions
