QUESTION Suppose that the function f is defined, for all real numbers, as follows. f (x ) = 2 if x #0 -4 if x=0 Graph the function f. EXPLANATION The function f is defined piecewise. More about This means that it is defined according to different rules depending on the input x. these rules The graph of f is the union of the 2 graphs shown below. . When x is not equal to 0, we have f (x) = -2. So this graph has a line passing through (0, -2) and (1, -2). But the point (0, -2) is not part of this graph. So we have a hollow dot at (0, -2). -5 4 -3 -2 -1 1 2 3 4 . When x is equal to 0, we have f (x) = -4. In other words, the point (0, -4) is part of this graph. So we have a solid dot at (0, -4).. When x is equal to 0, we have f (x) = -4. In other words, the point (0, -4) is part of this graph. So we have a solid dot at (0, - 4). -5 -4-3-2 2 3 - 2- The graph of f is the union of the graphs above. EO ANSWER 3- N -3 - 2 -3- -40 -5-Suppose that the function f is defined as follows. if - 1.5
