What Happens to ln(x^2 - 9) as x Approaches 3 from the Right?

[JFerra]

Determine the infinite limit:

lim ln (x^2 - 9)
x -> 3^+

Don't understand how the answer is negative infinity.

Thanks for the help

[╔(σ_σ)╝]

ln(ab) = ln(a) + ln(b).

That is what you need to understand your limit.

Note that x^2 -9 can be factored.
