Question

What is the domain of
\[f\]?
A coordinate plane. The x- and y-axes both scale by one. The function f is graphed on the coordinate plane. The following points are plotted: the point negative six, one, the point zero, four, the point two, negative five, the point four, three, and the point seven, three.
