Find the domain of the logarithmic function. \[ f(x)=\ln (8-x) \] (- (A) , 8) or $(8$, ) (- B .0) (c) $(-$ ,8) $(-8$, (D)

Step 1 ：Find the domain of the logarithmic function: \(f(x)=\ln (8-x)\)

Step 2 ：Since the natural logarithm is only defined for positive numbers, we need to find the values of x that will make the expression inside the logarithm \((8-x)\) positive.

Step 3 ：Solve the inequality: \(8-x > 0\)

Step 4 ：Add x to both sides: \(8 > x\)

Step 5 ：Final Answer: \(\boxed{(-\infty, 8)}\)
