Problem 24 in Gilat (4 points) 24. The graph of the function f(x) = ax +br + cx + d passes through the points (-1.2, 18.8), (0.2, 5), (2, 16), and (3.5, 15). Determine the constants a, b, c, and d. (Write a system of four equations with four unknowns, and use MAT- LAB to solve the equations.) Tips: Rewrite this as xa + x2*b+x"c+d y Four values of x and y are given: x=-1.2, y=18.8 X-0.2, y = 5 x-2, y = 16 x=3.5, y = 15 Write this in the form AX-B, where the X vector is the coefficients a, b, c, d
