You can put this solution on YOUR website! y= ln(x^2-1x-6)
----
You can only find the ln of a positive number.
---
Solve x^2-x-6 > 0
Factor:
(x-3)(x+2)> 0
---
Draw a number line and plot x=-2 and 3
---
Test a value from each of the line intervals
in the inequality to see where solutions lie.
---
Note: You need only test the signs since you are comparing to zero.
---
If x = -10 you get -*- > 0 ; true so solutions in (-inf,-2)
---
If x = 0 you get -*+ > 0 ; false
----
If x = 10 you get +*+ > 0; true so solutions in (3,+inf)
====
Domain: (-inf,-2)U(3,+inf)
