WebLet c= (a+b)/2be the middle of the interval (the midpoint or the point that bisects the interval). Then either f(a)and f(c), or f(c)and f(b)have opposite signs, and one has divided by two the size of the interval. Although the bisection method is robust, it gains one and only one bitof accuracy with each iteration. WebIf a root, a, has an odd multiplicity, then the polynomial's graph will cross through the x -axis at x = a. Both -3 and 5 have odd multiplicities, so the graph crosses through the x -axis at x...
