Commutative Property of Addition
g(x)=12x/x-5 ⇔ g(x)=60/x-5+12
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.
