FLASHCARD QUESTION

Front

What is the general form of a quadratic equation?

Back

The general form of a quadratic equation is ax² + bx + c = 0, where a, b, and c are constants and a ≠ 0.

FLASHCARD QUESTION

Front

What does the vertex of a parabola represent in a quadratic function?

Back

The vertex of a parabola represents the maximum or minimum point of the quadratic function, depending on the direction of the parabola.

3.

FLASHCARD QUESTION

Front

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

Back

For a quadratic function in standard form y = ax² + bx + c, the vertex can be found using the formula (-b/(2a), f(-b/(2a))).

FLASHCARD QUESTION

Front

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

Back

The discriminant (b² - 4ac) determines the nature of the roots of the quadratic equation: if it's positive, there are two real roots; if zero, one real root; if negative, no real roots.

FLASHCARD QUESTION

Front

What is the formula for the maximum height of a projectile given its initial velocity and height?

Back

The maximum height can be found using the formula h = -b²/(4a) + c, where h is the maximum height, and the quadratic function is in the form h(t) = at² + bt + c.

FLASHCARD QUESTION

Front

What does it mean for a quadratic function to have a negative leading coefficient?

Back

If a quadratic function has a negative leading coefficient (a < 0), the parabola opens downwards, indicating that it has a maximum point.

7.

FLASHCARD QUESTION

Front

How can you determine the x-intercepts of a quadratic function?

Back

The x-intercepts can be found by setting the quadratic equation equal to zero and solving for x, either by factoring, using the quadratic formula, or completing the square.
