Question 204384
Graph:
{{{f(x) = 1/(x-3)}}}
{{{graph(400,400,-5,5,-5,5,1/(x-3))}}}
The asymptote occurs at the x-coordinate whose value would make the function, {{{f(x) = 1/(x-3)}}} undefined and this would occur at x = 3 because this would make the denominator of the function equal to zero.
So the asymptote equation is:
{{{highlight(x = 3)}}}
