If one root of the equation f(x) = 0 is near to x0, then the first approximation of this root as calculated by Newton Raphson method is the abscissa of the point, where the following straight line intersects the x-axis”
1
The straight line through the point (x0, y = f(x0)) having the gradient \(\frac{1}{{f'\left( {{x_0}} \right)}}\)
2
Tangent to the curve y = f(x) at the point (x0, y = f(x0))
3
Passing through the point (x0, y = f(x0))
4
Normal to the curve y = f(x) at the point (x0, y = f(x0))
