Write a Matlab function for: 1. Root Finding: Calculate the root of the equation f(x)=x^3 −5x^2 +3x−7 Calculate the accuracy of the solution to 1 × 10−10. Find the number of iterations required to achieve this accuracy. Compute the root of the equation with the bisection method. Your program should output the following lines: • Bisection Method: Method converged to root X after Y iterations with a relative error of Z.
3. Use the bisection MATLAB program to estimate the roots of the function k(x) = x2 - 4, where x's range is [-1, 3). Include solutions for this method in the report. 4. Write a MATLAB program that uses the false-position method to estimate the roots of the function k(x) in problem#3. Include your m-file and solutions for this method in the report. In addition, submit your m-file separately.

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...
4. Consider the following partial information about a function f(x): S.x2, 0<x<I, (2-x), 1<x<2.
