X intercepts, Y intercepts, and Vertices

Front

What is the X intercept of a graph?

Back

The X intercept is the point where the graph crosses the X axis, meaning the value of Y is 0.

Front

What is the Y intercept of a graph?

Back

The Y intercept is the point where the graph crosses the Y axis, meaning the value of X is 0.

What is the vertex of a parabola?

Back

The vertex is the highest or lowest point of the parabola, depending on its orientation.

Front

How many vertices does a standard quadratic function have?

Back

A standard quadratic function has exactly one vertex.

Front

What does a minimum vertex indicate about the parabola?

Back

A minimum vertex indicates that the parabola opens upwards.

Front

What does a maximum vertex indicate about the parabola?

Back

A maximum vertex indicates that the parabola opens downwards.

Front

How can you determine if a vertex is a minimum or maximum?

Back

By examining the coefficient of the squared term in the quadratic equation; if it's positive, the vertex is a minimum; if negative, it's a maximum.

Front

What is the significance of the vertex in graphing a quadratic function?

Back

The vertex helps determine the direction of the parabola and the range of the function.
