Front

What is the range of a quadratic function that opens upwards and has a vertex at (0, -2)?

Back

All real numbers greater than or equal to -2.

Front

Using the graph of the function, identify the range if the lowest point is at y = -6.

Back

-6 ≤ y < ∞

Front

What is the definition of a y-intercept?

Back

The point where a graph intersects the y-axis.

Front

What does it mean if a quadratic function has two real solutions?

Back

The graph intersects the x-axis at two points.

Front

What is the vertex of a quadratic function?

Back

The highest or lowest point on the graph.

Front

How can you determine the number of solutions from a graph?

Back

By counting the number of times the graph intersects the x-axis.

Front

What is the axis of symmetry in a quadratic function?

Back

A vertical line that divides the graph into two mirror images.
