The graph represents a functional relationship.

On a coordinate plane, a straight line with a negative slope begins at point (1, 3), crosses the x-axis at (4, 0), and exits the plane at (18, negative 14).

Which value is an input of the function?

Mercury · Answer

Input values in an (x,y) coordinate system are the x-values

so simply compare your answer choices, along with the points listed on the graph, to see which number is also one of the x-coordinates on the graph
