Suppose f(x) is a function such that for some positive integer n, f has n linearly dependent derivatives. In other words, if f(x),f′(x),…,f(n−1)(x),f(n)(x) are all linearly dependent functions, then f(x) is expressible in terms of a,xk,eax,sin(ax),cos⁡(ax), and any combination of such functions, where a is a constant and k is a positive integer. Prove this statement
