A function f, which has derivatives for all orders for all real numbers, has a 3rd degree Taylor polynomial for f centered at x = 5. The 4th derivative of f satisfies the inequality f^(4)(x) ≤ 6 for all x the interval from 4.5 to 5 inclusive. Find the LaGrange error bound if the 3rd degree Taylor polynomial is used to estimate f(4.5). You must show your work but do not need to evaluate the remainder expression.
