Question 57098
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.
{{{graph(300,200,-10,10,-10,10,1/(x-3))}}}
Happy Calculating!!!
