Question

Domain of the function

Answer 1

F(x) = ln (6-x); find the domain.

The domain of the "ln" function is (0, infinity), or "x is greater than zero."

Thus, the domain of the given function is  "(6-x) is greater than zero."

Solve this:  6-x > 0.  Add x to both sides.  Then 6 > x, or x < 6 (answer)
