Question

How do you find the domain and range of `f(x)= log(x-2)`?

Answer 1

The domain of a function includes all possible `x` values of a function, and the range includes all possible `y` values of a function.

Explanation:

Domain: `(2,oo){x|x>2}` since `log` is undefined for `0` or negative values
Range: `(-oo,oo){y|yinRR}`

This can be verified with a graph:
graph{log(x-2)}
