16. On the interval [0, 2), find the coordinates of the relative minimum(s) of f(0) = 30-2 sin 0. The derivative of a function f(x) is f'(x) = (3-x) (x+5). Use this derivative for exercises 17 and 18. 17. At what value(s) of x does the graph of f(x) have a relative maximum? Justify your answer. 18. Use the equation of the tangent line to approximate the value of f(2.1) if f(2) = -3.
