Question 3 Use parabolic interpolation, solve for the value of x that maximizes the equation in Question 1. rx)=-1.5x6-2x4 + 12x Employ initial guesses of x1 = 0, x2 = 1, x3-2 and perform three iterations (Round the final answer to five decimal places). The question can be done in Matlab, Excel or using hand calculations. Provide your answers in a clear and concise manner and include Ea for each iteration
