(a) Use the graphs of the following functions to find the number of zeros they have on the interval O s 0 S 4n. (i) f(0) = 2 sin 0 + 1 vo L (ii) g(0) = 4 sin 0+ W N (iii) h(0) = -2 sin 0 4 5 (b) Assume that k > 0 and A# 0. How must A and k be related so that the function f(0) = A sin 0 + k has no zeros on this interval? IAL S v (c) Assume that k > 0 and A# 0. How must A and k be related so that the function f(0) = A sin 0 + k has exactly two zeros on this interval? IAl S e Textbook and Media
