Front

What is the standard form of a quadratic function?

Back

f(x) = ax² + bx + c

Front

What does the 'a' value in a quadratic function determine?

Back

The direction of the parabola (upward if a > 0, downward if a < 0).

Front

How do you find the axis of symmetry for a quadratic function?

Back

x = -b/(2a) where f(x) = ax² + bx + c.

Front

What is the formula to find the vertex of a quadratic function?

Back

Vertex: (h, k) where h = -b/(2a) and k = f(h).

Front

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

Back

It shifts the graph up or down without affecting the shape.
