All points of the step function f(x) are 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 3, 1) to (negative 2, 1). Each segment is 1 unit lower and 1 unit farther to the right than the previous segment. The right-most segment goes from (0, negative 2) to (1, negative 2).
What is the range of f(x)?
−3, −2, −1, 0, 1
−2, −1, 0, 1
all real numbers such that −3 < y ≤ 1
all real numbers such that −2 < y ≤ 1
