Question

What are the domain and range of f (x) = log (x minus 1) + 2?

Answer 1

`log(x - 1) + 2`

Domain:

The condition of log functions, is to set what's in between the brackets as being strictly greater than 0.

`x - 1 > 0`

`x > 1`

Domain:

`1 < x < \infty`

Range:

The range of log functions is all real numbers:

`- \infty < f(x) < \infty`

Answer 2

What are the domain and range of f (x) = log (x minus 1) + 2? It’s -6
