Numerical Methods y a0 a1x a2x2 a3x3 How many points are

Numerical Methods

y = a_0 + a_1x + a_2x^2 + a_3x^3 How many points are needed to solve for the above polynomial? A) You need four points. B) It doesn\'t matter how many points you have. You have four unknowns, so you need for equations. C) You need three points. D) You need five points.

Solution

Solution:

We can think that given equation has 4 constants that is a0, a1,a2, a3 and it has one variable x. This is a bi-quadriatic equation.

We will need 4 points to solve this equation since we have to find 4 constants and once we find the constants the equations will be ready.

So correct option is OPTION A
