Answer: f(2) is 3.

Step-by-step explanation:

f(2) just means "what is the vale of the function, f, when x = 2? Look for x=2 and read the y value where the line crosses x=2, in this case, the y value is 3. So f(2) = 3.

======

[One could also determine the equation for the line. Provided below.]

The slope is -(1/2) and the y-intercept is 4:

y = -(1/2)x + 4

For x=2,

y = -(1/2)*(2) + 4

y = 3

y(2) = 3

Answer:

10 liters of orange juice
5 liters of champagne

Step-by-step explanation:

Let c represent the number of liters of champagne Lauren uses. Then (15-c) will be the number of liters of orange juice. The total cost of the mix will be ...

12c +1.50(15-c) = 5.00(15)

10.5c = 52.50 . . . . . subtract 22.50, simplify

52.50/10.5 = c = 5 . . . . divide by the coefficient of c

Then the amount of orange juice is ...

15 -c = 15 -5 = 10 . . . . liters

Lauren should use 5 liters of champagne and 10 liters of orange juice.
