Given the numerical values shown for the function f(x), find approximate values for the derivative of f(x) at each of the xvalues given.
x= 0 1 2 3 4 5 6 7 8
f(x)= 13 15 16 17 17 14 11 9 7
f'(x)= 2 1 1 1 0 3 3 2 2
What seems to be the greatest rate of change of f(x)?
rate of change = _______
The task was to find f'(x), which I already did... but I thought that theh greatest rate of change was 3... how can I get the greatest rate of change???

Forget it... it's 2.. don't know why I thought it was 3 thanks anyways...
