3. (3) Consider the relation ln(x^2) = 0.7.

a. Use the graphical method in a MATLAB script to plot the relevant function of x spanning from 3 to 3 and state an approximation of its real and positive root. For this assignment, show the plot and your approximation of the root. You do not need to submit the MATLAB script.

b. Use the falseposition method in a MATLAB script, with an initial interval from +0.5 to 2, to approximate the root of the relevant function. For this assignment, show a table of the approximate roots and the approximate relative errors for three iterations. You do not need to submit the MATLAB script.
