#3. & #4: Your Turn!
Rose went to the state fair and had to buy coupons to play games. She bought a total of 50 coupons, and each game cost 10 coupons. The graph shows the number of coupons remaining as a function of the number of games played.
#3: Does this graph represent a discrete or continuous situation?
#4: What is the domain of this function?
#3: This graph represents a discrete situation. The number of coupons can only take on specific, individual values.
#4: The domain of this function would be the number of games played. Since each game costs 10 coupons, the domain would be all whole numbers starting from 0 (no games played) up to the maximum number of games that can be played with the given coupons.
