Best ResponseYou've already chosen the best response.0i think it's D b.c range is y and 9 is Y and it's a positive 9 so it should be 9 in more? someone should check me.. please

Best ResponseYou've already chosen the best response.0f(time)=a function of (number of video games) anyways the input time represents the domain and f(time) aka number of video games represents the range you said the domain was nonnegative values values like 0,1,2,3,4,... and so on... but if f(x) = 6x + 9 then f(0)=6(0)+9=9 and f(1)=6+9=15 and so on... so yes the outputs are 9 or more

Best ResponseYou've already chosen the best response.0and also nonnegative values can include decimal numbers but f(0)=9 and f(1/2)=6(1/2)+9=3+9=12 and f(1)=15 so anyways just trying to show it the number values are increasing starting at 9

Best ResponseYou've already chosen the best response.0\[f(x)=\frac{4x+1}{3} \\ f^{1}(3)=x \text{ implies } f(x)=3 \\ \text{ so replace } f(x) \text{ with } 3 \\ 3=\frac{4x+1}{3} \\ \text{ Solve for } x \]

Best ResponseYou've already chosen the best response.0yes 3(3)=4x+1 9=4x+1 8=4x x=2 so f(2)=3 which means \[f^{1}(3)=2\]

Best ResponseYou've already chosen the best response.0all the options had time being nonnegative f(x)=6x+9 would definitely have range y greater than or equal to 9

Best ResponseYou've already chosen the best response.0dw:1437704714373:dw yep for domain x greater than or equal to 0 we definitely have range is y greater than or equal to 9 that is a visual way to look at it a algebraic way is to do the following: we are given: \[x \ge 0 \\ \text{ multiply both sides by } 6 \\ 6x \ge 0 \\ \text{ add both sides by } 9 \\ 6x+9 \ge 9 \\ f(x)=6x+9 \\ \text{ so } f(x) \ge 9 \]

Best ResponseYou've already chosen the best response.0So if they didn't have the option where the range was y greater than or equal to 9 where the domain was nonnegative real numbers then they are actually wrong
