I have posted a link there to this topic so the OP can see my work.Suppose the line y = 5x − 2 is tangent to the curve y = f(x) when x = 4. If Newton's method is used to loc?Suppose the line y = 5x − 2 is tangent to the curve y = f(x) when x = 4. If Newton's method is used to locate a root of the equation f(x) = 0 and the initial approximation is x1 = 4, find the second approximation x2.

x2 = ___?___

___4.8, 4
