In matlab

2. Let f be the function f(x):= re-32 + (x/40) Return on one page plots of (a) y = f(x), -10 0 be small, then f(x+h)-f(x-h) f'(x) f"(t) = f(x+h) + f(x - 1) - 2f(x) 2h If you are courageous, consider using the Matlab commands diff and inline, as in: fs = 'x* 2 - x^3'; dfs = diff(fs) df = inline (afs)
