Front

What is the maximum height of a projectile in motion?

Back

The maximum height is reached at the vertex of the parabola represented by the equation of motion.

Front

When does a ball reach its maximum height in a quadratic function?

Front

How do you convert a quadratic equation to vertex form?

Back

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

Front

What is the vertex of the parabola represented by y = ax^2 + bx + c?

Back

The vertex is at (-b/(2a), f(-b/(2a))).

Front

What is the standard form of a quadratic equation?

Back

y = ax^2 + bx + c.

Front

What does the discriminant of a quadratic equation tell us?

Back

It indicates the nature of the roots: positive (two real roots), zero (one real root), negative (two complex roots).

Front

How do you find the roots of a quadratic equation?

Back

Use the quadratic formula: x = (-b ± √(b²-4ac)) / (2a).
