Question

A function is represented by the equation f(x)=−9x−1 . Determine the domain of this function. (1 point) Responses −∞<x<∞ −∞<x<∞ −∞<y<∞ −∞<y<∞ −∞<x≤0 −∞<x≤0 0≤x<∞

Answer 1

The function \( f(x) = -9x - 1 \) is a linear function. Linear functions are defined for all real numbers.

Therefore, the domain of the function \( f(x) \) is:

\[
-\infty < x < \infty
\]

So, the correct response is \( -\infty < x < \infty \).
