![1. Consider the function: f:R R defined by f()2z +5 cos(3z). (a) Compute the values f (0) and f(1). Does f have a root in the interval [0, 1]? (b) Apply the first three steps of the bisection method for f by hand. You can use a pocket calculator for computations. What is the absolute error for the solution at the end? (c) Use Matlab to approximate the root with an absolute error of e0.5-10-6. (d) Compute the values f(0) and f(2). Can you apply the bisection method on [0, 2]? With all the information learned so far about f, what can you say about the number of roots in the interval [0, 2]? please dont copy from an other expert answer](http://img.homeworklib.com/questions/78f532d0-bcea-11ea-906c-1d1820d1488c.png?x-oss-process=image/resize,w_560)

Questions: 1. Write a MATLAB program to find all the roots of a given, twice continuously differentiable, function f E C2[a, b]. Your program should first probe the function f(x) on the given interval to find out where it changes sign. (Thus, the program has, in addition to f itself, four other input arguments: a, b, the number nprobe of equidistant values between a and b at which f is probed, and a tolerance tol.) For each subinterval [ai,b] over...
