Domain:
Range:
Explanation:
Ok, lets start with the Domain
The domain of this equation is all numbers except when you divide by
Now we get
So at
That means that every other number you can think of will be valid for this function. Which gives us
Now to find the Range
The range can be found by dividing the leading coefficients from the numerator and the denominator. In the numerator we have
Since there is no number in front of the
So it would
So the range is
