Use synthetic division and the theorem on bounds to find integers a and b, such that the interval (a, b) contains all real zeros of the function. By inspecting the graph of each function, find the shortest interval (c, d) that contains all real zeros of the function with c and d integers. The second interval should be a subinterval of the first.y = x3 - 10x - 6
