Note that the given rational function is written in the form g(x)=b(x−h)1+k. Let's identify the transformations that the values of b, h, and k produce.
Constant | Condition | Transformation |
---|---|---|
b | 1<b | Horizontal shrink by a factor of b |
0<b<1 | Horizontal stretch by a factor of b | |
h | h<0 | Horizontal translation left h units |
h>0 | Horizontal translation right h units | |
k | k<0 | Vertical translation down k units |
k>0 | Vertical translation up k units |
Let's now identify the constants in the given function rule. g(x)=2(x−3)1+1 ⇔ g(x)=2(x−3)1+1 We can see that b = 21, h = 3, and k = 1. Therefore, the transformations of the parent function that result in the graph of the given function are a horizontal shrunk by a factor of 21, followed by a translation 3 units right and 1 unit up. These correspond to choices B, E, and G.
