Wendy is logging the number of video game levels she wins per hour. She has determined the function to be f(x) = 6x + 9, where x represents hours and f(x) represents the number of video game levels won. Which of the following options describes the restrictions to the domain and range correctly?
Domain, nonnegative values; range, values greater than −1.5
Domain, nonnegative values; range, values less than −1.5
Domain, nonnegative values; range, nonnegative values
Domain, nonnegative values; range, values greater than 9

Best ResponseYou've already chosen the best response.0You know the smallest number in the domain is 0 and f(x) is increasing with x. Plug 0 in for x in 6x + 9 to get the smallest number of the range.

Best ResponseYou've already chosen the best response.0I realize that she can do 0 hours of gaming, which would lead to 9 levels, yet , it told me that was wrong

Best ResponseYou've already chosen the best response.0I had chosen D, and it was marked wrong. :/

Best ResponseYou've already chosen the best response.0I guess they're looking for nonnegative values for the range, which doesn't quite make sense if they restricted the domain

Best ResponseYou've already chosen the best response.01.5 doesn't makes sense at all given the context b/c she can't play 1.5 games.
