12. Newton-Raphson method of solution of numerical equation is not preferred when
Graph of A(B) is vertical
Graph of x(y) is not parallel
The graph of f(x) is nearly horizontal-where it crosses the x-axis.
None of these
13. Following are the values of a function y(x) : y(-1) = 5, y(0), y(1) = 8 dy/dx at x = 0 as per Newton's central difference scheme is
0
1.5
2.0
3.0
