Front

What is the vertex of a quadratic graph?

Back

Front

What does the range of a quadratic function represent?

Back

The range of a quadratic function represents all possible output values (y-values) that the function can produce. For example, if the vertex is the maximum point and is at y = 3, the range would be y ≤ 3.

Front

How do you determine the maximum height of a projectile from its graph?

Back

The maximum height of a projectile can be determined from the vertex of its graph. The y-coordinate of the vertex represents the maximum height.

What is the quadratic formula?

Front

What does it mean if a quadratic equation has no real solutions?

Back

If a quadratic equation has no real solutions, it means that the graph of the equation does not intersect the x-axis. This occurs when the discriminant (b^2 - 4ac) is less than zero.

What is the significance of the discriminant in a quadratic equation?

Front

How do you find the axis of symmetry of a quadratic graph?

Front

What is a parabola?

Back

Front

What does it mean for a quadratic function to open upwards?

Back

A quadratic function opens upwards when the coefficient a is positive. This means the vertex is the minimum point of the graph.

Front

What does it mean for a quadratic function to open downwards?

Back

A quadratic function opens downwards when the coefficient a is negative. This means the vertex is the maximum point of the graph.
