Write a script newquot.m which uses the Newton quotient [f(x + h) (r)]/h to estimate the first derivative of f(x)-x' at x - 1, using suc- cessively smaller values of h: 1, 10-1, 10-2, etc. Use a function M-file for f (x) Rewrite newquot as a function M-file able to take a handle for f (x) as an input argument
