Answer Question 3:
3) a) Given that Images Not Shown
XX Images Not Shown XXXXX that Images Not Shown
Hence Images Not Shown
Plug i=X, 1,X,3,.......n in (**) so XXXX you get XXXXX (n+1) equations:
Images Not ShownXXXXXXX XXX above system in XXXXXX notation:
Images Not Shown
b) Put k=X,1,X,3 in p(k),
XXXX Images Not Shown
XXXXX the X degree polynomial p(x) XX XX follows:
Plugging XXXX data in XXXXXX notation (green) XXXX XXXX (a),
XXXXXXX XXXX gives
Putting these in (***) XXXXX XXX XXXXXXXX X XXXXXX polynomial
