Vertical Line Test Practice

Front

What is the Vertical Line Test?

Back

A method to determine if a curve is a function by checking if any vertical line intersects the curve more than once.

Front

If a vertical line intersects a graph at more than one point, what does that indicate?

Back

The graph does not represent a function.

Front

What does it mean for y to be a function of x?

Back

For every input x, there is exactly one output y.

Front

Can a vertical line intersect a function's graph more than once?

Back

No, if it does, the relation is not a function.

Front

What is an example of a function?

Back

y = 2x + 3, because for every x, there is one unique y.

What is an example of a relation that is not a function?

Back

y^2 = x, because for some x values, there are two corresponding y values.

Front

How can you visually identify a function on a graph?

Back

By using the Vertical Line Test; if any vertical line crosses the graph more than once, it is not a function.

Front

What is the definition of a function in mathematical terms?

Back

A relation where each input is associated with exactly one output.
