Question

Determine the domain of the function. F as a function of x is equal x divided by quantity x minus 9.

All real numbers except - 9
All real numbers
All real numbers except 9
x ≥ 0

Answer 1

Hey !!!

F is not possible when x - 9 (denominator) is 0.

x = 9 , then denominator becomes 0 .

therefore , All real no.s except 9

Answer 2

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
