Question

what does it mean if a graph passes the vertical line test? it is a function it is a linear function it is not a function

Explanation:

The vertical line test is a method to determine if a graph represents a function. If a vertical line intersects the graph at most once for any \( x \)-value, the graph passes the test. By definition, this means each input (\( x \)-value) has exactly one output (\( y \)-value), which is the property of a function. A linear function is a specific type of function (form \( y = mx + b \)), but passing the vertical line test only guarantees it's a function in general, not necessarily linear. Failing the test would mean it's not a function. So, passing implies it is a function.

Answer:

It is a function
