Question

determine if the relation why equals X4 minus one is a function by first graphing the relation, then applying the vertical line test. Enter one if the relation is a function. Enter two of the relation is not a function.

Answer 1

First, graph the relation y = x^4 - 1.

By looking at the graph, we can see that no vertical line intersects the curve more than once. Therefore, the relation y = x^4 - 1 passes the vertical line test and is a function.

So, the answer is 1.
