Answer:
(−∞, 2)∪(2, ∞)
Step-by-step explanation:
Domain is all the values that "x" can be
since finding all the values which "x" can be is too hard we will find out the values which "x" can't be- this means equating the denominator to "0" so that the function will be undetermined:
since we need the denominator to be "0" we must use the opposite of (-2) which is "2" so we will substitute "2" in the place of "x"- the function is now "undetermined" since nothing can be divided by 0 we need to write our answer in proper domain/range format
