FLASHCARD QUESTION

Front

What is the vertex form of a quadratic function?

Back

The vertex form of a quadratic function is f(x) = a(x-h)² + k, where (h, k) is the vertex of the parabola.

2.

FLASHCARD QUESTION

Front

What does the 'a' value in vertex form indicate?

Back

The 'a' value indicates the direction of the parabola (upward if a > 0, downward if a < 0) and the width of the parabola (narrower if |a| > 1, wider if |a| < 1).

3.

FLASHCARD QUESTION

Front

How does a positive 'a' value affect the graph of a quadratic function?

Back

A positive 'a' value causes the parabola to open upwards.

4.

FLASHCARD QUESTION

Front

How does a negative 'a' value affect the graph of a quadratic function?

Back

A negative 'a' value causes the parabola to open downwards.

5.

FLASHCARD QUESTION

Front

What transformation does the expression (x-h) represent in vertex form?

Back

The expression (x-h) represents a horizontal shift of the graph h units to the right if h is positive and to the left if h is negative.

FLASHCARD QUESTION

Front

What transformation does the '+k' represent in vertex form?

Back

The '+k' represents a vertical shift of the graph k units up if k is positive and down if k is negative.

7.

FLASHCARD QUESTION

Front

What is the axis of symmetry in a quadratic function in vertex form?

Back

The axis of symmetry is the vertical line x = h, where (h, k) is the vertex.
