Sign In
Start by dividing the numerator by the denominator.
Function: g(x)=1/x+1+2
Graph:
Graph of g as a Transformation of the Graph of f(x)= ax: Translation 1 unit left and 2 units up of the graph of f(x)= 1x.
We will rewrite the function, describe the graph of g as a transformation of the graph of f(x)= ax, and draw the graph of g.
2x/x= 2
Multiply term by divisor
Subtract down
The quotient is 2 with a remainder of 1. We can rewrite the function using this information. g(x)=2x+3/x+1 ⇔ g(x)=1/x+1+ 2
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)=1/x+1+2 ⇔ g(x)=1/x-( - 1)+ 2 We can see that a= 1, h= - 1, and k= 2. Therefore, the graph of g is a translation 1 unit left and 2 units up of the graph of f(x)= 1x. We will use this information to draw the graph.
