4. (5 points) Derive a global error bound for Forward Euler, accounting for numerical errors arising from finite-precision arithmetic. That is, suppose y(x) solves the IVP Jy' = f(x,y) .Let xo = a 0 (i.e., If (x, 21) - f(x, z2) | 0 so that ly"(a)| 0 be an upper bound on the finite precision error for each step of the method. Use the Forward Euler method with finite-precision yo = given error, [yit1 = yi + hf(xi, yi) + ci , where Vi leil 0 that minimizes E
