Use Newton''s method to find the second and third approximation of a root of x^3 + x + 3= 0 starting with x1 = -1 as the initial
BARSIC [14]

9514 1404 393

Answer:

  see attachment

Step-by-step explanation:

The iterator for Newton's method gives the next approximation (x') as ...

  x' = x -g(x)/g'(x) . . . . . where g'(x) is the derivative of g(x)

We have defined g(x) = x^3+x+3, the function we want the zero of. We have defined the iteration function to be f(x).

__

<em>Additional comment</em>

Modern graphing calculators not only make the iteration trivially simple, they also give a first approximation good to 2 or 3 decimal places in many cases.

Answer:

<em>Domain ⇒ All Real Numbers, Range ⇒ y < 0; Option D</em>

Step-by-step explanation:

Take a look at the procedure below;

First simplify f ( x ) = - 4 * ( 8 )^x, such that it is ⇒

f ( x ) = - 2^2 * 8^x,

f ( x ) = - 2^2 * ( 2^3 )^x,

f ( x ) = - 2^2 * 2^3x,

f ( x ) = - 2^2 + 3x,

Now if we take a look at the domain we can see that it has no undefined points nor domain constraints, thus;

- ∞ < x < ∞

However, the range of the function is present in the form - c * n^ax + b, where f ( x ) < k, and k = 0;

f ( k ) < 0, y < 0

<em>Solution; Domain ⇒ All Real Numbers, Range ⇒ y < 0; Option D</em>
