Answers
Answer:
a)largrange's formula
B) NEWTONS DIVIDED DIFFERENCE FORMULA
Explanation:
MARK ME BRAINLESTES
given values are below
X : 5 7 11 13 17
F(X) : 150 392 1452 2366 5202
=5, =7, =11, =13, =17
=150, =392, =1452, =2366 =5202
by using the lagrange's formula
put x=9
by using Newton's divide difference formula
solution : The divided differences table is
x y Δy Δy^2 Δy^3
5 150
7 392
11 1452
13 2366
17 5202
now we have taking x = 9 in the Newton’s divided difference formula,
f(9) =150 + (9 – 5) × 121 + (9 – 5)(9 – 7) × 24 + (9 – 5)(9 – 7)(9 – 11) × 1
= 150 + 484 +192 – 16 =810.
answer is 810.
