Is it possible to find the domain and range of the given function algebraically?

 

[MathLover1]

yes, you can plug in any positive or negative number for x and x^2,x^4, and x^6 will be positive number
and you already know that range of log function is always >=0

Almost looks like a cosine graph located differently.
