ISRO | ISRO CS 2009 | Question 45

The cubic polynomial y(x) which takes the following values: y(0) = 1, y(1) = 0, y(2) = 1 y(3) = 10 is

(A)

(B)

(C)

(D)

Answer:(A)
Explanation:

The answer can be obtained by substituting the values of x and checking for y(x): Option (A) is correct as:

x = 0: y(x) = 1
x = 1: y(x) = 0
x = 2: y(x) = 8 - 8 + 1 = 1
x = 3: y(x) = 27 - 18 + 1 = 10
