Coding problems: HW3_2 Given f(x)-x3-5x + 10 and g(x) = 4 sin(3x) + 6 Graph these two functions (using different colors for the lines) such that all intersection points are shown. Sol for the intersection points and plot them on the graph with black stars. Use fzero. HW3 3 The displacement, uy, along the simply supported beam shown below is given as -@k+)-3-238.25x -((x - (x-5)1)+(3-238.25x -() (xa_ (x-5)') + 75(x-7)2 + (-)z?-238.25x 3 (57 Plot this piecewise function. Use fzero to find the x location of the maximum displacement. Print the answer to the screen using fprintf 20 kips/ft
