Find the the x and y intercepts the maximum and minimum (graphically) of the function f(x) = -2x2 - 7x + 4/4x2 + 2 x = line space (-52, 25) To answer graph the function, (experiment with the viewing window if you have to) and then find the x and y coordinates of the requested 4 points with 3 correct decimal digits by repeated zooming. On your test sheet make a sketch of your graph and label your 4 points on the graph. Find the roots of the polynomial f(x) = x4 + 3x3 - 14x + 5. You can select which method you are using, but you have to write down how did you get your answers. Be careful! Find the limit when x rightarrow 0 of the following function step by step as follows h(x) = 5(1 - cos2x)/x sin x Make an m-file which calculates the above function. Write down the commands, which makes your m -file. Use your m-file to calculate your function at x = pi /4 and x = pi /3 and write down what your get, before starting to use. your m-file. Calculate left limit for x rightarrow 0 in a table form, use format long . Write down you commands. Do the same thing for right limit. (No need to repeat the commands on the test sheet) Explain what you did. Copy a few item from your table to your test sheet. What is your conclusion. f You can do it with calculus as well for extra credit, if you do it both ways. Solve the following equation: (-4.581,21) ,(4.581,21) x2 + cos2x = 21 You have to solve the problem by graphing and zooming. First you have to think about the interval where you would display your function. Write down your commands and the coordinates of your solution with 3 correct decimal digits. Explain how you get your interval where you decide to graph your function.Explanation / Answer
Will post an answer very soon . will solve all the bits in matlab woth commented solution.
