Question 57098: How can you show a graph that approaches negative infinty as x approaches 3 from the left?
Thank you. Answer by funmath(2933) (Show Source):
You can put this solution on YOUR website! How can you show a graph that approaches negative infinty as x approaches 3 from the left?
The function that I'm going to show you is:
f(x)=1/(x-3)
If x-3=0 the function is undefined, resulting in a vertical asymptote at x=3. The program draws in that vertical asymptote, but it's not rally part of the graph. Notice that if you travel along the x axis from the left, you will dive towards negative infinity. If you travel along the x axis from the right you will shoot up towards positive infinity.
Happy Calculating!!!
