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.
