Let's say I have any unknown function

and I know its value for some x i.e.

for

x=1:10

is

f(x)=[a b c d e f g h i j k l m]

where

are some numerical values.

Can I calculate derivative of

at

with this given data?

if ‘a,b,c’ are numerical values and not functrions of ‘x’, the derivative would be uniformly 0.
