# How do you graph #f(x)=(x-2) / (x+2)#?

##### 1 Answer

Just to run through some general points:

What is f(x) when x = 0?

Thus our first point on the graph is (0,-1).

What is x at 1?

Thus our second point on the graph is (1, -1/3).

We continue in this manner until you have enough points on the graph.

#### Explanation:

One thing to note: when

As we can see on the y axis, when x is positive it never reaches

graph{(x-2)/(x+2) [-10, 10, -5, 5]}
