Front

What is the standard form of a quadratic equation?

Back

y = ax² + bx + c, where a, b, and c are constants.

Front

What does the coefficient 'a' indicate in a quadratic equation?

Back

It determines the direction of the parabola: if a > 0, it opens up; if a < 0, it opens down.

Front

How do you find the vertex of a quadratic function in standard form?

Back

Use the formula x = -b/(2a) to find the x-coordinate, then substitute back to find the y-coordinate.
