Respuesta :
The function is not defined when the denominator (x-9) is zero. The denominator will be zero when x=9, so that value must be excluded from the domain.
The domain is ...
... All real numbers except 9
Hey !!!
F is not possible when x - 9 (denominator) is 0.
x = 9 , then denominator becomes 0 .
therefore , All real no.s except 9
