FLASHCARD QUESTION

Front

What is the vertex form of a quadratic function?

Back

The vertex form of a quadratic function 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' in the vertex form y = a(x - h)² + k represent?

Back

The 'a' value determines the direction and width 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 y = a(x - h)² + k?

Back

The vertex is found at the point (h, k).

4.

FLASHCARD QUESTION

Front

What is the axis of symmetry in the vertex form y = a(x - h)² + k?

Back

The axis of symmetry is the vertical line x = h.

5.

FLASHCARD QUESTION

Front

If a quadratic function opens upwards, what can you say about the value of 'a'?

Back

If the quadratic function opens upwards, the value of 'a' is positive.

FLASHCARD QUESTION

Front

What is the vertex of the function y = (x + 2)² - 4?

Back

The vertex is (-2, -4).

7.

FLASHCARD QUESTION

Front

What is the vertex of the function y = -3(x - 1)² + 5?

Back

The vertex is (1, 5).
