a. Show that if x and y are sufficiently close to zero and f is differentiable at (0, 0), then fa. y) * f(0,0) +xf. (0, 0) + yf, (0, 0). b. Use the approximation formula in part a to show that 1-x+y 1+x-y for smalx and y. C. Ifx and y are sufficiently close to zero, what is the approx- imate value of the expression x+1)2+ (y+ 1)2
