Consider the function f(x)= log1/2 ( x^2-2x-3) and determine :
( A ) Its domain.
( B ) The intervals where it is strictly increasing.
( C ) The intervals where it is strictly decreasing.
I think that the domain is (-infinity,-1) the parenthesis after -1 is supposed to be a bracket. I have some trouble finding the range...and the intervals?:S
