Front

What is the vertex form of a quadratic equation?

Back

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

Front

What does the discriminant tell us about the roots of a quadratic equation?

Back

If b² - 4ac > 0, there are 2 real roots; = 0, 1 real root; < 0, no real roots.

Front

What is the axis of symmetry for a quadratic function?

Back

x = -b/(2a) for the equation ax² + bx + c.

Front

How do you find the maximum or minimum value of a quadratic function?

Back

Use the vertex form or find the vertex (h, k) where k is the max/min value.

Front

What is the standard form of a quadratic equation?

Back

y = ax² + bx + c.
