= 5. Consider the problem y h(x1, x) = x1x2 of multiplying two nonzero real numbers. On a computer the algorithm for approximating the product is yA = hA(x1, x2) = f(x1) fl(x2), where is the inexact floating point multiplication. Show that the algorithm is backwards stable. That is, show hA(x1, x2) = h(x1 + 8x1, x2 + 8x2), where 8x1/x1 = O(Emach) and 6x2/x2] = 0(Emach). Is the perturbation of the inputs unique?
