Best ResponseYou've already chosen the best response.1One way is to make a table of xy values if x = 0, then y = 2x1 y = 2*01 y = 01 y = 1 y = 1 dw:1443149349193:dw

Best ResponseYou've already chosen the best response.1do that with a few more x values to get more points. Then plot all of the points on the xy plane and draw a curve through them

Best ResponseYou've already chosen the best response.0Thank you very much. Do you know how I would figure out the domain and range?

Best ResponseYou've already chosen the best response.0It looks like a v but i was always confused about the domain and range.

Best ResponseYou've already chosen the best response.1are there any restricted x values?

Best ResponseYou've already chosen the best response.1ie are there any x values that lead to division by zero errors? or things like that?

jim_thompson5910

Best ResponseYou've already chosen the best response.1because there are no restrictions, this means the domain is the set of all real numbers

Best ResponseYou've already chosen the best response.1you can plug in any real number you want, and some result will pop out for y

Best ResponseYou've already chosen the best response.0so thats the domain? How do i figure out range?

Best ResponseYou've already chosen the best response.1notice how on the graph, the graph stretches infinitely to the left and right along the x axis

Best ResponseYou've already chosen the best response.1as for the range, look for the lowest point. What is that lowest point?

jim_thompson5910

Best ResponseYou've already chosen the best response.1yes, that's the vertex notice the y coordinate of this point is y = 0 this is the lowest the graph goes. So the range is \(\Large y \ge 0\) y can be any number as long as it's greater than or equal to 0

Best ResponseYou've already chosen the best response.1in interval notation, the range would be \(\Large [0, \infty)\) start at 0 (include 0) stop at infinity (exclude infinity)
