Question 2 Consider the function f: [-1, 1] → R f(x) = (x - 1)ª ln(x²+x+1), where a, b are the last two digits of your student number, which are greater than 1. The shape of the function is complicated enough that it is hard to draw using hand calculations. You will use Taylor polynomials to approximate different parts of the function to estimate the shape of its graph and to approximate some stationary points. If you wish you can use a graphing calculator or an app or web site to see the computed shape of the graph, however, this is not necessary and your answer should contain only information you have calculated below, not information from another source. It is fine to use a normal calculator if you need to find the decimal expression of a value to plot it. (a) Write down f(x) for your a and b (and use it for this and the remaining questions). Calculate the first and second derivatives f'(x) and f"(z) (no need to simplify the expressions). (b) Calculate the three different second-order Taylor polynomials (T₂f)(z) centred around three r-values: r = -1, r=0 and x = 1. Show all working. (e) Either by hand, or by using a computer program, draw the three graphs of second-order Taylor polynomials determined in (b), in one figure.
