A florist is making bouquets of flowers for a wedding. Each bouquet will have 9 flowers. The graph shows the linear relationship between y, the number of flowers used, and x, the number of bouquets. The florist will use no more than 8 bouquets for the wedding. Which set best represents the domain of the function for the situation?

• {0,2,4,6,8,10}

• {0,1,2,3,4,5,6,7,8}

• {0,18,36,54,72,90}

• {0,9,18,27,36,45,54,63,72}

A coach has 96 golf balls for the school's golf team. The coach will give each player on the team 8 golf balls. The graph shows the linear relationship between y, the number of golf balls remaining for the team, and x, the number of players on the team. The coach will use no more than 6 players on the school's golf team. Which set best represents the range of the function for this situation?

• {96,84,72,60,48,36,24}

• {8,9,10,11,12,13,14}

• {96,88,80,72,64,56, 48}

• {0,1,2,3,4,5,6}
