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

How do you identify the vertex from the vertex form?

Back

The vertex (h, k) can be directly identified from the vertex form y = a(x-h)² + k.

3.

FLASHCARD QUESTION

Front

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

Back

The parameter 'a' indicates the direction and width of the parabola. If 'a' is positive, the parabola opens upwards; if negative, it opens downwards.

4.

FLASHCARD QUESTION

Front

What is the axis of symmetry in a quadratic function?

Back

The axis of symmetry is a vertical line that passes through the vertex of the parabola, given by the equation x = h.

5.

FLASHCARD QUESTION

Front

How do you find the x-intercepts of a quadratic function in vertex form?

Back

To find the x-intercepts, set y = 0 and solve the equation 0 = a(x-h)² + k.

6.

FLASHCARD QUESTION

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex represents the maximum or minimum point of the parabola, depending on the value of 'a'.

7.

FLASHCARD QUESTION

Front

What is the maximum or minimum value of a quadratic function in vertex form?

Back

The maximum or minimum value is the y-coordinate of the vertex (k). It is a maximum if 'a' is negative and a minimum if 'a' is positive.
