Answer 2

Answer:

Forward difference operator A= E-1, where E is the shift operator.

Step-by-step explanation:

Forward difference operator

A[f(x)] = f(x+h)-f(x)

Shift operator

E[f(x)]= f(x+h)

Then, relation between forward difference operator and shift operator is given by

Af(x) = f(x+h) - f(x)

= E* f(x) - f(x)

= (E-1)*f(x)

Hence,

A=E-1
