$(-oo,oo)$

Since $f(x) = 2x+6$ is a line there are no restrictions on the function's input so the domain is all real numbers $(RR)$ or interval notation:

$(-oo,oo)$

graph{2x+6 [-13.21, 6.79, -3.08, 6.92]}

$x inRR$

$y=2x+6$

$"is a linear function with no restrictions on it's domain"$

$"domain "x inRR$
graph{2x+6 [-10, 10, -5, 5]}
