Best ResponseYou've already chosen the best response.1I recommend using a graphing calculator. If you don't have something like a TI83, then you can use a free graphing website like desmos https://www.desmos.com/calculator

Best ResponseYou've already chosen the best response.0i have one, i can graph them, i just really need help with the domain and range.

Best ResponseYou've already chosen the best response.1do you see how the graph extends infinitely in both directions in the horizontal (x axis) direction?

Best ResponseYou've already chosen the best response.1What that tells us is that the domain is the set of all real numbers. You can plug in any number you want for x and it's a valid input.

Best ResponseYou've already chosen the best response.0yes, it suppose to look wavy too right? since i graph it in radian?

Best ResponseYou've already chosen the best response.0okay good. so the domain would just be all real numbers?

Best ResponseYou've already chosen the best response.1how about the range?

Best ResponseYou've already chosen the best response.1you sure? every y value is a possible output?

Best ResponseYou've already chosen the best response.0wait, will it be (0,5) since that the only whole y number i got?

Best ResponseYou've already chosen the best response.1look at the lowest and highest points. What are the y coordinates of those points?

Best ResponseYou've already chosen the best response.0im lost at this point, the X values go on forever, how do i find the highest and lowests?

Best ResponseYou've already chosen the best response.0so wait, the range is between the 2 most nearest whole numbers?

Best ResponseYou've already chosen the best response.1the range is between 6 and 4 because these are the possible y values that pop out of the function. No other y value is possible. We can't have y = 0 for instance

Best ResponseYou've already chosen the best response.1we write the range as \[\Large 6 \le y \le 4\] which in interval notation is [6,4]
