Question

PLEASE PLEASE HELP - 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?

Answer 1

Well she cannot win negative levels, so you cannot go below the x axis, and she cannot play negative games so she cannot go to the left of the y axis

Answer 2

Medal? :)

Answer 3

The domain cannot be less than 0, and the range cannot be less then zero due to the reasons described

Answer 4

so what wouldd the answer be? i kinda get it

Answer 5

these are answer choices ill give a medal!

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

Answer 6

So you cannot play negative games right? So your line cannot go below the X axis because its negative right? So the restriction is it cannot go below the x axis, or it cannot go below y=0. And she cannot play negative games, so she cannot go to the left of the y axis, or cannot go below x=0

Answer 7

Domain, nonnegative values; range, nonnegative values

Answer 8

so it would be the bottom answer right? its greater than 0

Answer 9

Because it cannot be negative numbers

Answer 10

ahh ok thanks so much
