A person wants to order ferns for his garden. He checked the price at a nursery and found that the nursery charges 89 for delivery and $5 for each plant ordered. He also noted that there are no delivery charges for an order of $70 or more. Based on his findings, he wrote the following functions:
. f(n) = 9+5n to represent the cost of n plants when a delivery charge is included
· g(n) = 5n to represent the cost of n plants with no delivery charge
Match the domain to the function
All positive integers All positive integers less than 14 All integers greater than or equal to 70 All positive integers less than 70 All integers greater than or equal to 14
All non-negative integers less than 14 All non-negative integers less than 70
