... −π and 2π and a y-intercept of −2. (a) Draw a graph of f  . (b) Write an equation for f  . This equation should have no unknown constants. (c) On the graph you drew in part (a), go back and ... encountered in the case of functions f , g, and h above. Now consider the functions j(x)= 1 x for x = 0 and 0 for x = 0ork(x ) = (x 2 ) for x = 0 and 1 for x = 0, both res...

To change the amplitude of a sine or cosine ... versa). We know how to shift a function vertically and how to stretch and shrink both hori- zontally and vertically, so we simply apply our knowledge to these ne...
