1. A transformed cosine function, given by g(x)= a cos [2(x+30)] + c has a maximum value of 9 and a minimum value of 5. There is no reflection about the x-axis, so that a 0. a) ]Determine the value of c. b) Determine the value of a. c) List the transformation that were applied to the present function f(x)= cos (x) to obtain g(x) d) Sketch the graph of g(x) and f(x). Domain (x ER-180 x 180) 2) Given the following different presentations of a relation, explain how to tell if the underlying relation is a function in each case. Give an example of each .a)] Graphs: b) ] Tables of values
