Find the change in y, Ay when a = 1 and Ax = 0.3 Find the differential dy when x = 1 and dx = 0.30 Question 11 v [Z 1 pt '0 1 Consider the function f(:r:) 2 124 983:2 + 9, 6 Consider the function f(a:) = cos(27r:c) on the interval [1,0]. Evaluate this function at the endpoints of the interval. Does Rolle's Theorem apply to f on this interval? 0 No C) Yes If Rolle's Theorem applies, find c in (1, 0) such that f'(c) = 0. If Rolle's Theorem does not apply, enter "DNE". c=_ 0 Question 2 v I Below is the function x).
