standard, vertex, and factored form

Front

What is the axis of symmetry in a quadratic function?

Back

The axis of symmetry is a vertical line that passes through the vertex of the parabola.

Front

What does the vertex of a parabola represent?

Back

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

How do you find the vertex from the standard form?

Back

Front

Back

It represents a reflection across the x-axis, a vertical compression by 1/5, a shift right 1 unit, and a shift up 7 units.

Front

What does it mean to reflect a function across the x-axis?

Back

Reflecting across the x-axis means that for every point (x, y) on the graph, the point (x, -y) will also be on the graph.

What is the effect of a positive 'a' value in a quadratic function?

Back

A positive 'a' value indicates that the parabola opens upwards.
