Table below shows the tabulated data based on the experiment to determine the relationship between mass molarity of polypropylene with refractive index of solution. Based on these data, the function can be generated as followed. x f(x) 0 0 1 0.5 2 0.8 3 0.9 4 0.951176 5 0.961538 x2 f(x) = (1 + x2) Determine the value of x that corresponds to f(x) = 0.93 numerically and analytically. Compare the accuracy.
