(Ax-1) Below is a graph of this function formulated as a roots problem f(x) = 0 with the parameter A 3. 0.8 0.6 0.4 0.2 0.2 0.4. 0.6 0.8 -1 0.1 0.2 0.3 0.4 0.5 0.6 0.7 Question 5 1 pts Which of the following anonymous function definitions would be the correct option for input to a root finding function like bisect_param.m along with the value of A passed as a parameter through varargin. ( f = @(xA) expl2"X)."(1-x2)-explA"x-1) O f= @(xA) expl2"X)."(1.x2) fx)- exp(2"x). (1-x. 2)-exp(Ax-1) O f = @(Ax) expl2"x)."(1-x2)-exp(A"X-1) Question 7 0/1 pts Below are several options for an initial guess bracket to send to the bisection method to solve for the root with A 3. Select all of the options for which bisection is GUARANTEED to converge to the root xl-0.6, xu 0.7 Bisection is not guaranteed to converge on the root for any of these options xl=0, xu = 0.5 xl 0.5, xu 0.7 Question8 0/1 pts Suppose you want to solve for the root using Newton-Raphson. For which of the initial guesses below is Newton-Raphson likely to fail to converge on the root located near x 0.6 xi 0.1 xi 0.7 Newton-Raphson is likely to fail to converge to the root near 0.6 for all of these initial guess options. xi 0.5 xi 0.4
