Determine if the relation y = 4 - 1 is a function by first graphing the relation, then applying the
vertical line test. Enter 1 if the relation is a function. Enter 2 if the relation is not a function. (1 point)
The relation is given by y = 4 - 1. By simplifying, we have y = 3.
To graph the relation, we plot points where y = 3. It means that for every x-value we choose, the corresponding y-value will always be 3.
So the graph is a horizontal line passing through y = 3.
Now, we can apply the vertical line test. The vertical line test states that if any vertical line intersects the graph in more than one point, then the graph does not represent a function.
For this graph, if we draw any vertical line, it will only intersect the graph at one point, as the graph is a straight horizontal line.
Therefore, the relation y = 3 is a function.
The answer is 1.
