Question
A function can be modeled by the equation g(x)=6x−14
. Which gives the domain of the function?(1 point)
Responses

−∞<x<0

negative infinity less than x less than 0

−3≤x≤3

negative 3 less-than-or-equal-to x less-than-or-equal-to 3

−∞<y<∞

Answer 1

A linear function g(x)=6x−14 is defined for every real x, so the domain is all real numbers: −∞ < x < ∞.

None of the first two choices match that exactly. The choice "−∞ < y < ∞" uses y instead of x but represents "all real numbers," so that's the closest — correctly written it should be "−∞ < x < ∞."
