Given that the graph represents the equation y = 4, which is a horizontal line, we can analyze its characteristics:

Analysis of the graph

1.Is it a Function?

A relation is a function if each input ( x ) has exactly one output ( y ).

The line ( y = 4 ) passes the vertical line test; any vertical line drawn will intersect the line at exactly one point for all ( x ). Therefore, it is a function.

2.One-to-One Function?
