Q1) For f(x) = sinx, Os X s 2nt. What is the maximum instantaneous rate of * 1 point change? Where does it happen? 1, at X = nt/2 O It, at X = 2nt O It, at X = 1 1, at x = 0 Q2) For f(x) = sinx, when is the instantaneous rate of change 0? Choose the * 1 point best answer. X = nn, NEZ x = 2nnt, NEZ x = (n - 1/2) n, NEZ x = (2n + 1/2) 1, nez Q3) For f(x) = cosx (x > 0), when is the instantaneous rate of change -1? * 1 point Choose the best answer. X = nn, NEZ O X = 2nn, n EZ O X = (n - 1/2) n, NEZ x = (2n + 1/2) n, NEZQ4) What is the equation of the tangent line for f(x) = ain2x, at x = D? *
