Question
Program in C
on nction is defined as follows:
X = X-1
f(x)
f'(x)
k = 1,2,...
Start with the initial approximation x = 3.
(1)
If f(x), f (x), and f(x) are continuous near the root r, and f (r) = 0, then if the
initial approximation is chosen close enough to r, the sequence {x} defined in (1)
will converge to r.
Test your Newton-Raphson program on the polynomial
p(x) = x² - 6x +8x³+8x² + 4x − 4

Develop a program that implements the POLYNOMIAL ADT using the LIST ADT.
The POLYNOMIAL ADT is used to represent polynomials and the following operations
defined on polynomials:
1. Evaluate(p(x), =). Evaluates the polynomial p(x) at the point x = z and returns
the result.
2. Add(P₁(x), P₂(x)). Returns the polynomial that results when p₁(x) is added
to P₂ (x).
3. Subtract(p, (x), p₂(x)). Returns the polynomial that results when p, (x) is
subtracted from p₂(x).
4. Multiply(p₁(x), p₂(x)). Returns the polynomial that results when p₁(x) is
multiplied by p₂(x).
5. Differentiate( p(x)). Returns the polynomial that results when p(x) is
differentiated.
Use your POLYNOMIAL ADT implementation to find a real root of a given
polynomial using the Newton-Raphson method. For a given function f(x), the Newton-
Raphson iteration function is defined as follows:
X = X-1
f(xx-1)
f'(xx-1)'
k = 1,2,...
