this is how u do it

Answer 2

Answer:

The domain is $[7,9)$.

Step-by-step explanation:

We are given the equation.

$f(x)=\sqrt{\frac{x-7}{9-x} }$

Domain is the set of values of $x$ satisfying the given equality.

It is clear that the denominator cannot be zero.

Hence, $9-x\neq 0$

$x\neq 9$

Also, the value inside the root should be positive, otherwise it will give negative values.

$x-7 > =0$

$x > =7$

and

$9-x > 0$

$x < 9$

So, the domain is $[7,9)$.
