What is the function notation that describes the relationship between the total cost C(g) and the number of gallons purchased g at a gas station?

The function notation that describes the relationship between the total cost C(g) and the number of gallons purchased g at a gas station is:

C(g)

The function notation that describes the relationship between the total cost C(g) and the number of gallons purchased g at a gas station is typically written as C(g). The letter "C" represents the total cost and "g" represents the number of gallons purchased.

To find the specific function notation for this relationship, you would need more information about the pricing structure at the gas station. Most gasoline stations charge a fixed price per gallon, so the function C(g) would likely be a linear function in this case.

For example, if the price is $2 per gallon, the function would be: C(g) = 2g. This means that the total cost C is equal to the number of gallons purchased g multiplied by the price per gallon, which in this case is $2.
