The function, f(x), is plotted below. On a coordinate plane, a curve opens up and to the right in quadrants 2 and 1. It approaches x = negative 1, goes through (0, 1), and approaches the x-axis in quadrant 1. A second curve opens down and to the left. It approaches the x-axis in quadrant 3, goes through (negative 2, negative 1), and approaches x = negative 1 in quadrant 3. Evaluate each limit, if it exists. Limit as x approaches negative 1 minusf(x) = -1 Limit as x approaches negative 1 plusf(x) =
