What is the standard form of a quadratic equation?

Back

y = ax² + bx + c

Front

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

Back

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

Front

How do you find the y-intercept of a quadratic function?

Back

Set x = 0 in the equation.

Front

What is the vertex form of a quadratic equation?

Back

y = a(x-h)² + k, where (h, k) is the vertex.

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

Back

It determines the nature of the roots: positive (two real roots), zero (one real root), negative (no real roots).
