Because of the vertical asymptotes, we can see that the correct option is D.
Which rational function is graphed?
First, we can see that we have two vertical asymptotes at x = 3 and x = -3, so the denominator becomes equal to zero for these two values.
Then the function is something of the form:
[tex]f(x) = \frac{a}{(x - 3)*(x + 3)}[/tex]
Where a is a constant.
The only option in this form is D, so the correct option is:
[tex]f(x) = \frac{1}{(x - 3)*(x + 3)}[/tex]
