please help me filling the gaps,

5 4 -2 - 0 2 -2 -3 Suppose you have an unknown mystery function f(x). The GeoGebra app above does not show the function f(x), but it does show (in blue) the nth degree Taylor polynomial Pn (x) for f(x) about the point x = 0 . The mystery function f(x) lies somewhere in the grey shaded area, which is the area between the functions n(x) i) What is the smallest value of n such that pn(x) has three stationary points? n =| Number ii) What is our best guess for f(z)?1 iii) What is our best guess forf (-r/2)? iv) Ah ha! The mystery function is f(x) =
