what is the domain and range for ln(x^2 - x - 6)??

Answer 1

domain: x^2-x-6>0,
x^2-x-6= 0,
x= ((1+-5))/2, x = 3 or x =-2
i.e. x^2 -x -6 =( x-3) (x+2) >0 then
x>3 OR x<-2
(-infinity, -2) U (3, infinity)

range = (-infinity, infinity)

Answer 2

domain x^2-x-6>0 x^2-x-6= 0 x= ((1+-5))/2
so x>3 and x<-2
Range from -infinity to+ infinity
