How do you approach a logarithm question with absolute value at its base?

So I'm a third year high school student and I'm stuck at this question. How do you approach this logarithm to get the domain of x?



log|1x|(x+5)>2



The answer is 1<x<0 and 2<x<4



Also, how do you graph the logarithm function with an absolute value? I tried desmos but it doesnt seem to allow adding absolute value in the log base.

Thank you very much.
