A nonlinear function f(x) is defined in the interval -1.2 < x < 4 as illustrated in the figure below. The equation f(x) = 0 is solved for x within this interval by using the Newton-Raphson iterative scheme. Among the initial guesses (I1, I2, I3, and I4), the guess that is likely to lead to the root most rapidly is
