I have to graph -4/x-4 and then find the domain, range, and if it is a function or not. I know how to do the ones with 1 as the numerator, but not -4. I have to do this by hand by the way. Any help is greatly appreciated!
The -4 in the numerator, '-' is a reflection in the x-axis with a dilation factor of 4.
To find the domain and range you need to determine the asymptotes.
This is where the relation is not defined. Do you know how to find that?
Hint: The denominator cannot be zero.
