the step function f(x) is graphed what is the value of f(-1)? The graph is attached in the picture below the answer choices areA. -3B. -1C. 0D. 1

Notice that on interval [-1,1), the function is defined as the constant f(x) = -1.
Then, notice that on the graph, the point (-1,-1) corresponds to the image of f(-1).
Therefore, f(-1) = -1
