6. (Piecewise Linear Function. Consider a function which is defined on the interval (0,2] such that it is continuous and linear on the intervals (0, 1) and (1, 2), separately. Such a function can be uniquely determined from the y-values when I is 0, 1, and 2. See the figure below for a sample of how such functions look. (1.4) (2, 92) Ko, 9.) 7x 2. piecewise_linear.m Script: Input variables: yo. yi, and y2 holding the y values x holding an r coordinate satisfying 0 > y = 0; >> y1 = 1; >> y2 = 0; >> X = 0.5; >> piecewise_linear y = 0.50000
