Plot the following function in MATLAB:

y = f(x) = ln(x^4) - 0.7

and convince yourself that f(x) has a unique positive root.

Determine this root using the method of false-position, with the initial bracketing interval [xl, xu], and the stopping criterion es as input in MATLAB.

Note: es denotes the maximum allowable approximate absolute percent relative error in the root
