With 3 points we can describe a polynomial of degree 2 .
so our desired polynomial is of the form y=ax2 + bx + c.
plugging the above given values in the above quadratic equation we get
5 = a x 0 + b x 0 + c
=> c = 5.
6 = a x 1 x 1 + b x 1 +c
=> 6 = a+ b + c
but c = 5
so a + b = 1
also
8 = a x 2 x 2 + b x 2 +c
8 = 4a + 2b + 5
but a+b = 1 using this we get
b = 1/2 , a = 1/2, also c = 5
using these values we get value for P(3) as:
(1/2) x 3 x 3 + (1/2) x 3 +5
9/2 + 3/2 +5 = 1
