Graph:
Graph of g as a Transformation of the Graph of f(x)= ax: Translation 5 units right and 12 units up of the graph of f(x)= 60x.
We want to rewrite the given rational function so that it is in the form g(x)= ax-h+k. We will do it by inspection.
a = a+ 60- 60

Commutative Property of Addition
We have found an equivalent expression for g.
Let's start by recalling two possible transformations of the function f(x)= ax.
| Function | Transformation of the Graph of f(x)= ax |
|---|---|
| g(x)=a/x- h | Horizontal translation by h units. If h>0, the translation is to the right. If h<0, the translation is to the left. |
| g(x)=a/x+ k | Vertical translation by k units. If k>0, the translation is up. If k<0, the translation is down. |
Now consider the obtained equation. g(x)=60/x- 5+ 12 We can see that a= 60, h= 5, and k= 12. Therefore, the graph of g is a translation 5 units right and 12 units up of the graph of f(x)= 60x. We will use this information to draw the graph.
