5. Given the function f (z) = - cos(21 + T) (a) Determine the amplitude. (b) Determine the period. (c) Determine the phase shift. (d) Label the axes and graph the function on the graph below for the interval [-7, 7], adding extra tick marks if necessary. (e) On the same graph, graph the function y = ? sec(2x + T) +10. Use a right triangle to write each expression as an algebraic expression. Assume that I is positive and that the given inverse trigonometric function is defined for the expression in c. sec | sin 1 Vx2 + 4
