Question

functions unit test

determine if the relation y=4x-1 is a function by first graphing the relation then applying the vertical line test enter 1 is the relation is a function enter 2 if its not a function.

Answer 1

2, the relation is not a function.

Answer 2

r u sure??

Answer 3

Yes, I am sure. The relation y=4x-1 is a linear equation, which means it is a straight line. When graphed, the line will be diagonal and not vertical. Therefore, the vertical line test will show that the relation is not a function because a vertical line will intersect the graph in more than one point.

Answer 4

wait so it is a functino or not?

Answer 5

Apologies for the confusion. Let me clarify: The relation y=4x-1 is a function. Since it is a linear equation, each input (x-value) corresponds to exactly one output (y-value), and a vertical line will only intersect the graph at one point. Therefore, based on the vertical line test, the relation y=4x-1 is indeed a function.
