Which point should have an open circle in the graph of the piecewise function f(x)={−x−1 if x<1−x+2 if x≥1?
1 answer
An open circle should be used to indicate a point where the function is not defined. In this case, the graph of the piecewise function is defined for all real numbers. Therefore, there should not be an open circle on any point in the graph.
