idk is correct

IDK IS CORRCT!! 100%

this is for the function quiz right for connexus

The correct function notation to describe the relationship between the total cost (C) and the number of gallons purchased (g) would be:

B. g = 2.19C(g)

This notation indicates that the number of gallons purchased (g) is equal to 2.19 times the total cost (C) of the gas. It represents the input-output relationship, where the total cost is the output and the number of gallons purchased is the input.

How do you get the answer?
