Use Newton's method with initial approximation x1 = −2 to find x2, the second approximation to the root of the equation x3 + x +
rjkz [21]

Answer:

The value of x_2=-1.6923.

Step-by-step explanation:

Consider the provided information.

The provided formula is f(x)=x^3+x+6

Substitute x_1=-2 in above equation.

f(x_1)=(-2)^3+(-2)+6

f(x_1)=-8-2+6

f(x_1)=-4

Differentiate the provided function and calculate the value of f'(x_1)

f'(x)=3x^2+1

f'(x)=3(-2)^2+1

f'(x)=13

The Newton iteration formula: x_2=x_1-\frac{f(x_1)}{f'(x_1)}

Substitute the respective values in the above formula.

x_2=-2-\frac{(-4)}{13}

x_2=-2+0.3077

x_2=-1.6923

Hence, the value of x_2=-1.6923.
