Unformatted text preview: Reflection of Functions about the xAxis The graph of ( ) y f x = is obtained by reflecting the graph of ( ) y f x = about the xaxis. Reflections of Functions about the yAxis The graph of ( ) y f x =is obtained by reflecting the graph of ( ) y f x = about the yaxis. Objective 4: Using Vertical Stretches and Compressions to Graph Functions Vertical Stretches and Compressions of Functions Suppose a is a positive real number: The graph of ( ) y af x = is obtained by the multiplying each ycoordinate of ( ) y f x = by a . If 1 a , the graph of ( ) y af x = is a vertical stretch of the graph of ( ) y f x = . If 0 1 a < < , the graph of ( ) y af x = is a vertical compression of the graph of ( ) y f x = . 3.4.17 and 27 and 41 and 53 Use the graph of a basic function and a combination of transformations to sketch each of the functions. _________________________________...
