Front

What is the vertex of the quadratic function y = -\frac{1}{2}(x-3)^2 + 2?

Back

The vertex of the function is (3, 2).

Front

What does it mean for a quadratic to be symmetric about the vertex?

Back

A quadratic function is symmetric about its vertex, meaning that the left side of the parabola is a mirror image of the right side.

What is the general shape of a parabola when a > 0?

Back

When a > 0, the parabola opens upwards.

Front

What is the general shape of a parabola when a < 0?
