81-82 Graphing Transformations If f(x) = v 2x ->2, graph the following functions in the viewing rectangle [-5, 5] by [-4, 4]. How is each graph related to the graph in part (a)? 81. (a) y = f(I) (b) y = f(21) (C) y =1 (2x) Answer * 87a) y - f(x) (b) y = f (-z) (c) y - - f ( -I) (d) y - f( 2x) (e) y- f ( 52)
