1) To find the domain we have to check whether this function has values that return into undefinitions within the Real Set. Rewrite it as a function:
2) Since the only constraint for that logarithms is that the value of x >0
Then we can write:
3) D= x > 0,
Writing it as interval notation, since x>0 then x can't be negative so we can final
D =(0, ∞)
