Question

Use the vertical- line Test to determine which graph represents a function? I'm thinking it's the first one...

Answer 1

The graph 2 represents the function that passes the vertical line test. Graph 2 is a function.

Further explanation:

Explanation:

The function is defined as for every value of the range has exactly one pre-image in the domain.

If we put a vertical line on the graph of the function and if it passes the other line at 1 point that means the graph of the function passes the vertical line test.

A function always passes the vertical line test as well as the horizontal line test.

Graph 1 doesn’t pass the vertical line test. Therefore, it is not a function.

Graph 2 does pass the vertical line test. Therefore, it is a function.

Graph 3 doesn’t pass the vertical line test. Therefore, it is not a function.

Graph 4 doesn’t pass the vertical line test. Therefore, it is not a function.

The graph D represents the function that passes the vertical line test. Graph D is a function.

Answer 2

Its gonna be the 2nd one...the one  horizontal line.
The reason is a function is not gonna have any repeating x values...they can have repeating y values, just not the x ones. All the other graphs have repeating x values...so they are not functions
