Algebra 2 - Domain and Range

Front

What is the domain of a function?

Back

The domain is the set of all x-values included in the function.

Front

What happens to the vertex of a parabola when it opens downward?

Back

The vertex is a maximum.

Front

What are the roots of a graph?

Back

The roots are the x-values where the graph intersects the x-axis.

Front

What is the vertex of a parabola?

Back

The vertex is the highest or lowest point on the graph of the parabola.

Front

What is the green dot on the parabola called?

Back

The green dot represents the maximum or minimum of the parabola.

Front

How do you determine the domain of a function from its graph?

Back

The domain can be found by identifying all the x-values that the graph covers.

Front

What is the range of a function?

Back

The range is the set of all y-values that the function can output.

Front

How do you find the range of a parabola that opens upward?

Back

The range starts from the y-coordinate of the vertex and goes to positive infinity.

Front

What is a maximum in the context of a parabola?

Back

A maximum is the highest point on the graph of a parabola that opens downward.

Front

What is a minimum in the context of a parabola?

Back

A minimum is the lowest point on the graph of a parabola that opens upward.
