1. This exercise concerns writing a function determinant.m that recursively computes the determinant of a square matrix. Verify if the following function is correct.

2. Create a function M-file for f(x) = x^3−3x−k that takes a user- defined value of constant k and then find the minimum value of f(x) in the range 0 ≤ x ≤ 2 using fminbnd.
