Best ResponseYou've already chosen the best response.1You plug the domain values into the function, one at a time, and your result is included in the range. Example, here is the first one:\[\large\rm f(1)=4(1)1\]\[\large\rm f(1)=5\]So our range looks like this so far: \(\large\rm\{5,~~,~~,~~,~~\}\) Where the domain value of 1 corresponds to the range value of 5. Make sense? :o

Best ResponseYou've already chosen the best response.1so would the next one be 3?

Best ResponseYou've already chosen the best response.1For the domain value x=0, Hmm no we don't get 3 for the range. Did you mean the one after that? :o

Best ResponseYou've already chosen the best response.1Yes I did, was there more solving to do on the other one?

Best ResponseYou've already chosen the best response.1No, you just skipped a number :) I did 1, 0 comes after that, then 1, < this is the one you did then 2, then 3

Best ResponseYou've already chosen the best response.1I thought I was doing the one for 0, I don't know how it became the next ones answer

Best ResponseYou've already chosen the best response.1Oh you thought you were doing 0? Ok maybe a little math error then :) let's check.\[\large\rm f(0)=4(0)1\]4 times 0, is 0,\[\large\rm f(0)=01\]So that's not giving us 3, right? :)

Best ResponseYou've already chosen the best response.1I think I might have subtracted 1 from 4 when I was supposed to multiply 4 by 0

Best ResponseYou've already chosen the best response.1So what do you get for that next one? :)

Best ResponseYou've already chosen the best response.1Looks like 1, ya? 01 = 1 \[\large\rm\{5,1,~~,~~,~~\}\] How bout when you plug x=1 into the function?

Best ResponseYou've already chosen the best response.1this time it would be three because 1 x 4 is 41= 3

Best ResponseYou've already chosen the best response.1\[\large\rm Range:\{5,1,~3,~~,~~\}\]Ah there we go :)

Best ResponseYou've already chosen the best response.1yay good job \c:/\[\large\rm Range:\{5,1,~3,~7,11\}\]
