The function, f(x), is plotted below. On a coordinate plane, a curve starts at open circle (negative 1, 1), increases to (negative 2, 2), and decreases through (negative 3, 1). A horizontal line goes from closed circle (negative 1, 2) to open circle (1, 2). A closed circle is at (1, negative 2). An open circle is at (1, 1) and a line goes down to (2, 0), increases to (3, 2), and decreases down through (5, negative 1). Evaluate the limits, if they exist. If not, write DNE. Limit as x approaches negative 1 minusf(x) = Limit as x approaches 3 plusf(x) = Limit as x approaches 1 f(x) =
