Q18 Write an expression in E notation for the 15th Taylor polynomial of f(x) = e centered at c = ()Q22 Suppose you are using Taylor polynomials of f(x) centered at a = 0) to approximate f (-3). However, for each k, the best bound you can put on f()(x) on [-3, 0] is #. Will you be able to guarantee a good approximation of f(-3) this way? Explain.Q26 Let f (x) = Vr. Write the degree 2 Taylor polynomial of f centered at I = 8. b If you wanted to use the Taylor polynomial to approximate v10, how would you do that
