Front

What is the standard form of a quadratic equation?

Back

y = ax^2 + bx + c

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.

Front

What is the quadratic formula used for?

Back

To find the roots of a quadratic equation, given by x = (-b ± √(b² - 4ac)) / (2a).

Front

What does the discriminant of a quadratic equation tell you?

Back

It indicates the nature of the roots: if positive, two real roots; if zero, one real root; if negative, no real roots.

Front

What is the axis of symmetry in a quadratic function?

Back

The vertical line that divides the parabola into two mirror images, given by x = -b/(2a).
