Question

9-Х+3/Х+3 знайти область визначення

Answer 1

Ответ:

$\frac{12 - x}{x + 3}$

Объяснение:

$\frac{9 - x + 3}{x + 3} \\ 9 + 3 = 12$

$\boxed{Ответ:{\boxed{\green{ \frac{12 - x}{x + 3}} }}}$

Answer 2

Finding the Domain of the Function

To find the domain of the function 9x - 3/x + 3, we need to determine the values of x for which the function is defined.

The function contains a fraction with x in the denominator. For a fraction to be defined, the denominator cannot be equal to zero. Therefore, we need to find the values of x that make the denominator (x + 3) equal to zero and exclude those values from the domain.

To find the values of x that make the denominator zero, we can set (x + 3) = 0 and solve for x:

(x + 3) = 0

Solving for x, we get:

x = -3

Therefore, the function is undefined when x = -3. We need to exclude this value from the domain.

The domain of the function is all real numbers except x = -3.

Domain of the Function:

The domain of the function 9x - 3/x + 3 is all real numbers except x = -3.
