To stretch or shrink the graph in the y direction, multiply or divide the output by a constant. 2f (x) is stretched in the y direction by a factor of 2, and f (x) is shrunk in the y direction by a factor of 2 (or stretched by a factor of ). Here are the graphs of y = f (x), y = 2f (x), and y = x.
$403.75
Step 1: 415(.15)
Step 2: 475 - 415(.15)
Step 3: 403.75
0.43 is greater because you need 7 to get to 0.5 unlike 0.42 where you need 8
