(a)Suppose that the tangent line to the curve y = f (x) at the point (3, −11) has equation y = −5 − 2x. If Newton's method is used to locate a root of the equation f (x) = 0 and the initial approximation is x1 = 3,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 = −6, and the tangent line to f (x) at x = 9 passes through the point (18, 5), find f (9).
(c)Use Newton's method with initial approximation x1 = 4 to find x2, the second approximation to the root of the equation x3 = 7x + 5.
(a) The second approximation x 2 will be: -2.5 (b) The value of f ( 9 ) = 1... View the full answer
- B appears to be wrong :/

- Information is missing, because there is not information about slope of tangent line, so i assumed the previous equation of tangent
