Answer 1

The table represents a function, if every input (x) has only ONE output (y)

∵ The size 1.7 cubic feet has a price of $80

∵ The size 2.7 cubic feet has a price of $94

∵ The size 3 cubic feet has a price of $100

∵ The size 3.2 cubic feet has a price of $105

∵ The size 3.6 cubic feet has a price of $115

∴ Each size has ONE price

∴ Each input has only ONE output

∴ The table represents a function

The answer is YES

The answer is B
