Question

Is the graph increasing, decreasing, or constant?

Answer 1

The graph is consistent because it isn’t going up or down (changing).

Answer 2

Constant function.

Explanation:

The graph shows a horizontal line, where clearly all values of the variable plotted on the vertical are the same (constant = -4) for all values of the horizontal coordinate. Since y doesn't change, we refer to this function as a constant function.
