Question 4*+If \(f(4)=9\) and \(f'(4)=-1\), find \(a_0\) and \(a_1\) for the Taylor series about \(4\).
Question 11***+A Taylor series about \(1\) begins \(4+6(x-1)-3(x-1)^2\). Find \(f(1)\), \(f'(1)\), and \(f''(1)\).
Question 19*****Show that coefficients depend on the centre by writing \(x^2\) about \(0\) and about \(1\).
Question 20*****Explain how \(a_0\), \(a_1\), and \(a_2\) encode value, slope, and curvature in a Taylor model.
