Answer:
Discrepancy = 665,15 L
Step-by-step explanation:
Data: 1 Apple Barrel: 7056 cubic inches
1 Cranberry Barrel: 5826 cubic inches
The merchant sells 33 cranberry barrels, so we need to find out the total volume of that. So we multiply our cranberry volume (data) 33 times:
33 x 5826 cubic inches = 192258 cubic inches
Now, the customer thinks that he is receiveing apple barrels. To calculate this volume, we need to multiply the apple volume (data) 33 times:
33 x 7056 cubic inches = 232848 cubic inches
(You can see that 33 apple barrels have more volume that 33 cranberry barrels, so the customer will receive less volume than he is expecting)
The problem is asking the discrepancy in the shipment in liters (L). First we calculate the discrepancy (difference) in cubic inches.
Discrepancy (cubic inches) = 232848 cubic inches - 192258 cubic inches = 40590 cubic inches
Finally we need to transform the units. As a general rule, we know that:
1 litre (L) = 61,0237 cubic inches. Using a simple rule of three we can solve it:
Discrepancy (L) = x 1 L
Discrepancy (L) = 665,15 L

Answer:
A. f^-1(x) = x³ -12
Step-by-step explanation:
The inverse function can be found by solving ...
x = f(y)
x = ∛(y +12) . . . . . use the definition of f(x)
x³ = y +12 . . . . . . . cube both sides to eliminate the radical
x³ -12 = y . . . . . . . add -12 to isolate the y-variable
f^-1(x) = x³ -12 . . . matches choice A
