Question

What is the domain of the function represented by the graph?

On a coordinate plane, a line goes through (0, negative 2) and (4, negative 1).
all real numbers
Negative 4 less-than-or-equal-to x less-than-or-equal-to 4
Negative 3 less-than-or-equal-to y less-than-or-equal-to negative 1
y less-than 0

Answer 1

All real numbers.

Reason: the graph is a straight line (extends indefinitely left and right), so x can be any real number (domain = (-∞, ∞)).
