For this case the first thing you should do is observe the value of the function on the y-axis when the value of x is -2. We observe that when x = -2 we have two possible values: y = 1 y = 3 The value of y = 1 is discarded because we have a piecewise function with a gap in y = 1. Therefore, this value is not part of the range of the function. The value of y = 3 is part of the range of the function. Answer: When x=-2 the y value is: f (-2) = 3 B. 3
