Question about MATLAB boundary value problem.

How can I solve the following problems? I would appreciate if you could briefly explain how you get the answer. (In the second problem, the selected answer is not correct.)

Given the differential equation: u" + 2u' - xu = 0 subject to the boundary conditions: du/dx (x = 0) = 4 u(x = 5) = 10 This is to be solved using a second-order accurate in space method with x = 0.1. Which of the follow equations represents the equation for an interior node? 0.9ui-i - (2 + 0.01 xi)ui + l.lui+1 = 0 0.9ui-i - 2ui + 1.9ui+1 = 0 (2 - 0.01xi)ui - 2.2ui-i + ui-2 = 0 0.5ui-1 - (2 + 0.25xi) ui + 1.5ui+i = 0
