    R (all real numbers)

    range: {y element R : y>=0} (all non-negative real numbers)

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

    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

    What does the graph of this function look like?

    Almost looks like a cosine graph located differently.
