(a) | Suppose that the tangent line to the curve y =
f (x) at the point (−9, 53) has equation
y = −1 − 6x. If Newton's method is used to locate
a root of the equation f (x) = 0 and the initial
approximation is x1 = −9, find the second
approximation x2. |
(b) | Suppose that Newton's method is used to locate a root of the
equation f (x) = 0 with initial approximation
x1 = 9. If the second approximation is found to
be x2 = −2, and the tangent line to
f (x) at x = 9 passes through the point
(17, 6), find f (9). |
(c) | Use Newton's method with initial approximation x1 = 2 to find x2, the second approximation to the root of the equation x3 = 6x + 6. |
