domain is $(- \infty, 10)$ $(-oo,10)$

Domain of f(x) would be all values of x along the number line, except at those points where f(x) does not exist.

Accordingly, in this case f(x) does not exist for $x \geq 10$ $x>=10$

Hence domain is $(- \infty, 10)$ $(-oo,10)$

How do you find the domain of f(x)=ln(10−x)f(x) = ln (10-x)?
