19 Mark this question A graph with an x-axis ranging from 6 to 6 and a y-axis ranging from 2 to 10. The graph has a parabolic portion and a W-shaped curve. The parabolic portion begins from an open circle at (0, 4), peaks at (2, 6), and descends into the fourth quadrant by crossing the x-axis between 5 and 6. The curve descends from the second quadrant to the point x equals 3, reaches a peak at (2, 2), and then descends to the point x equals 1. From here, the curve extends upward, reaching the closed dot at (0, 6). For the graph shown below, find all values of x for which f left parenthesis x right parenthesis is not differentiable. x equals 0 f left parenthesis x right parenthesis is differentiable for all x-values. x equals short dash 3 comma space x equals short dash 1 x equals short dash 3 comma space equals short dash 1 comma space x equals 0
