Extracted text: Let the function f(x, y) = Vx - Vy. Fix y = 1 and let x = 1+ 8,, & small but greater than machine e. • Show that P S(x, y) > • Write code to plot f(x, y) versus 8. Let & range from single precision epsilon to double precision epsilon. Also plot the upper and lower bounds from the first part. • Come up with a different arithmetic set of operations that gives you the same f(x, y) but is more accurate. Plot this function for the same range of 8.
