The interpolating polynomial p(r) of degree 4 of f(r) = 6x - 2r+ 9 is p(x) = 6z- 2z +9. Select one: O True False An algorithm is called stable iff Select one: O a. A small change in the input results sometimes in a significant change in the output. Ob.A small change in the input results always in a significant change in the output. OC.A small change in the input results always in a small change in the output. Given the following data in the form (r, f(r)): (1.10, 1), (1.20, 2), (1.28, 3), (1.30, 4). Using the appropriate formula of order O(h2) to approximate f'(1.30), we get Select one: O a. f'(1.30)~ 25 O b. f'(1.30) = 10 O c. f'(1.30) = 25 O d. f'(1.30)- 10 O e. f'(1.30) 50 O f f'(1.30) = 50
