Answer 1

In the expression, f(x) = y, the x component is the dependent variable while y is the independent variable. In this case, in the expression f(2) = 6, 2 is the dependent variable in which this case, the number of candies. The total cost depends on the number of candies bought. Hence the answer is A. A) The total cost of 2 candies is $6.00.

Answer 2

The correct answer is:

A) The total cost of 2 candies is $6.00.

Step-by-step explanation:

We are told that f(x) represents the cost of candy, and that x represents the number of candies.

f(2) means that x=2, which is 2 candies; f(2) = 6 means that the cost of 2 candies is $6.
