1. Graph f(x) = cos (x) . 2. Use what you know about graph transformations, graph g(x) = sin (x+ - ) . Does this look familiar? 3. Use what you know about graph transformations to graph h(x) = cos (-x) . Can you deter- mine if cos(x) is even or odd by looking at this graph? 4. Use what you know about graph transformations to graph k(x) = sin (-x) and ((x) = - sin(x). Can you determine if sin(x) is even or odd by looking at these graphs
