Let f(x) = ax (x 1) In (x + 2) be a real valued function defined over the interval (-2, +00) 1. Use the Matlab-Plot function to plot the graph of f over the interval (1,2) Include your Matlab codes and your graph. 2. In order to approximate the root r of f located in the interval (1, 2): (a) Compute 2 Iterations to and r, using the Bisection method. Show your computations below (b) Write Newton's formula first, then compute 2 Iterations r2 and r3 using Newton's method.( Letr be the Initial condition.)Show your computations below (c) Write the Secant formula first, then compute 2 Iterations ra and rs using the Secant method. (Letry and rz be the Initial conditions. Show your computations below Express all your answers in Normalised floating point form, with a precision p= 6 and rounding to the closest.
