the step function f(x) is graphed.

on a coordinate plane, a step graph has horizontal segments that are each 1 unit long. the left end of each segment is a closed circle. the right end of each segment is an open circle. the left-most segment goes from (negative 5, 3) to (negative 4, 3). each segment is 1 unit lower and 1 unit farther to the right than the previous segment. the right-most segment goes from (2, negative 4) to (3, negative 4).

what is the value of f(0)?
