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]}
