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 at more than one point.

Front

If a graph passes the Vertical Line Test, what can we conclude?

Back

The graph represents a function.

Front

If a graph does not pass the Vertical Line Test, what can we conclude?

Back

The graph does not represent a function.

Front

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

Back

For every x-value, there is exactly one corresponding y-value.

No, if it does, then it is not a function.

Front

What is an example of a function?

Back

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

What is an example of a non-function?

Back

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