Question

What are the domain and range of the function f(x) = -log(5-x)+92

O domain: x <5
range: 129
O domain: x <5
range: (-0.00)
O domain: x29
range:
(-0.00)
domain: 29
range: y29

Answer 1

Second Option

Explanation:

The argument of the log must be greater than zero so

`5 - x > 0`

`-x > - 5`

`x < 5`

So our domain is All Reals less than 5.

The range of log function is all reals so the answer is -oo, oo).

So the second option is the answer.
