We can first graph the equation y = 4x - 1 by plotting a few points.
When x = 0, y = -1
When x = 1, y = 3
When x = 2, y = 7
After plotting these points, we can see that the graph of y = 4x - 1 is a straight line.
Next, we can apply the vertical line test to determine if the relation is a function. The vertical line test states that if any vertical line intersects a graph at more than one point, then the graph does not represent a function.
In this case, when we draw vertical lines through the graph of y = 4x - 1, each vertical line intersects the graph at only one point. Therefore, the relation y = 4x - 1 is a function.
Therefore, the correct answer is 1.
