Decide whether the given relation is a function of x. (NO CREDIT WILL BE GIVEN WITHOUT AN EXPLANATION). Give the domain. y=-7/x-16

Answer 1

If you meant
y = -7/(x-16), then the domain is

any real number, x ≠ 16

and for every x you pick there is one and only one value of y , except x=16
so it is a function.
