We know the answer is B, because we would need to divide the 20 by 4 and the 12 by 4 in order to see the equal amounts of balls each friend has.
The limit from the left is equal to the value of the function:
.. f(0) = 0
The limit from the right is the value that x^2 approaches as x approaches 0. That is 0^2 = 0.
Left and right limits are the same, so the limit as x approaches zero is 0.
