The value of is:
therefore the composite function fog is:
as we know that the domain of the function is the set of values of the independent variable for which the function is defined.
so we can notice that the composite function is defined when the denominator of is not equal to zero.
therefore the composite function is defined for all values of x except x=-15.
therefore the domain of the composite function is
therefore the second option is correct.
