To determine if the relationship y = 4x - 1 is a function, we first need to graph it.
The graph of y = 4x - 1 is a straight line with a slope of 4 and a y-intercept of -1.
Next, we apply the vertical line test to determine if the relation is a function. The vertical line test states that if any vertical line intersects the graph at more than one point, then the relation is not a function.
In the case of y = 4x - 1, because it is a straight line, every vertical line will intersect the graph at only one point. Therefore, the relationship y = 4x - 1 is a function.
So, the answer is 2: the relation is a function.
