How do you find the domain and range of #f(x) = - ( 1 / ( x + 1) ) #?
1 Answer
Domain:
Range:
Using interval notations
Domain:
Range:
Explanation:
We are given the function
To find the Domain of
We must remember that
So, our Domain is
To find the Range of
Let us now observe our original function
We note that there is no x term in the numerator(NR)
Hence, the degree of numerator is ZERO(0).
The highest degree of the denominator(DR) is ONE(1).
We observe that degree of the DR
Hence, we conclude that
Range:
Range using interval notations is
