FLASHCARD QUESTION
Front
What is the vertex form of a quadratic equation?
Back
The vertex form of a quadratic equation is given by y = a(x - h)² + k, where (h, k) is the vertex of the parabola.
2.
FLASHCARD QUESTION
Front
What does the 'a' value in the vertex form indicate about the parabola?
Back
The 'a' value determines the direction of the parabola: if 'a' is positive, the parabola opens upwards; if 'a' is negative, it opens downwards.

FLASHCARD QUESTION
Front
How do you find the vertex from the vertex form equation y = a(x - h)² + k?
Back
The vertex is the point (h, k) in the equation.
4.
FLASHCARD QUESTION
Front
What is the effect of changing the 'k' value in the vertex form equation?
Back
Changing the 'k' value shifts the parabola up or down on the graph.
5.
FLASHCARD QUESTION
Front
What is the effect of changing the 'h' value in the vertex form equation?
Back
Changing the 'h' value shifts the parabola left or right on the graph.

FLASHCARD QUESTION
Front
If a quadratic equation is in the form y = -2(x + 3)² + 5, what is the vertex?
Back
The vertex is (-3, 5).

FLASHCARD QUESTION
Front
What does it mean if a parabola has a maximum value?
Back
A parabola has a maximum value if it opens downwards, meaning the vertex is the highest point on the graph.
