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