What are the domain and range of this function?


f(x)= 3/5x^5


The picture below shows the options for answers...please help me get this practice right so I have a full understanding when I take a test next week, thank you!!!!

I think this is


3 / [ 5x^5 ]


The domain is  everything but x = 0  [it makes the denominator = 0 ]

So ...domain is  (-inf, 0 ) u (0, inf)


The range is a little trickier

We have a lower degree polynomial / higher degree polynomial

Whenever this happens..in the absence of any other shift up/down...we will have a horizontal asymptote of y = 0

So...the range is  (-inf, 0) U (0, inf)

Thank you very much! I agree, figuring out the range was a little more difficult for me to understand. Good explanation!
