The figure shows the graph of a function $ f $. Suppose that Newton's method is used to approximately the root $ s $ of the equation $ f(x) = 0 $ with initial approximaton $ x_1 = 6 $.

(a) Draw the tangent lines that are used to find $ x_2 $ and $ x_3 $, and estimate the numerical values of $ x_2 $ and $ x_3 $.

(b) Would $ x_1 = 8 $ be a better first approximation? Explain.

(a) $$

x_{2} \approx 7.3 \quad x_{3} \approx 6.8

$$

(b) 6

This doesn't explain much... Wish the video included a description of what is actually going on in the problem, rather than just giving the solution.

Okay, a As you can see, they would have tangent ones that look like us. We estimate x two to be 7.15 and expose three to be 6.85 X three is relatively close to us. Okay, Part B. The answer to this would be yes. X one equals a is a better approximation. And using X one equals sex. The value of X three is close to survive s than X three resulting from X one equals sex.
