Question

Help fast plizz! What are the domain and range of the function f(x)=log(x-4)-3?

Answer 1

Domain: (4, ∞)

Range: (-∞, ∞)

Explanation:

In this logarithmic function, the
`(x-4)` in parenthesis is where the function moves to in the x direction. The direction is always opposite because you would set that expression to 0 and solve for x, giving you 4. The function, though, approaches 4 and never reaches it.

The range is all real numbers because the function continues to go downward and upward to infinity.
