Question

As we can see the function can take all the values on the number line ( as there is no point where the function is not defined ) the domain is all real numbers

Great! Thanks.  How should I go about finding the range?

anonymous · Answer

Nevermind... :P haha

ok what i would do for this function is graph it..

Now we know it tale values for all real numbers, so there is no point where the function is not defined so we do not have to worry of it.. 

Also i can see it is a cubic function, so a cubic function ranges all over from - infinity to +infinity
