Determine if the relation y=4x−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

The relation y = 4x - 1 is a function because when graphed, it passes the vertical line test - any vertical line drawn on the graph will only intersect the relation at one point.

your sure?

Yes, I am sure. The relation y = 4x - 1 is a function because it passes the vertical line test, meaning each input x has only one corresponding output y.
