means function of x. (30 marks) Question 2. (40 marks) 2.1. 2.2. 2.3. It may not be known in advance where the roots are for a general function. Discuss incremental search and bracketing procedure and what are potential problems. Illustrate potential incremental search hazards plotting in MATLAB different functions of your choice. (20 marks) Plot the function f(x) = x2x2 + x between -2 and 2. How many roots does this function have? Find these roots using MATLAB roots built-in program (use command help roots in the command window to learn more about MATLAB roots program). (10 marks) Read about Matlab built-in fzero program (use command help fzero in the command window, material from Lecture 3 notes and/or on internet). Test the Matlab program fzero finding real roots of functions given in questions.1. and in 2.2. In order to estimate position of real roots, first plot the functions f(x). If you have time, you can test Matlab program fzero for couple of your own functions f(x). (10 marks) MacBook Pro
