FLASHCARD QUESTION

Front

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

Back

The axis of symmetry for a quadratic function in vertex form, y = a(x-h)² + k, is the vertical line x = h.

2.

FLASHCARD QUESTION

Front

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

Back

The vertex of a quadratic function in vertex form, y = a(x-h)² + k, is the point (h, k).

3.

FLASHCARD QUESTION

Front

What is the standard form of a quadratic function?

Back

The standard form of a quadratic function is f(x) = ax² + bx + c, where a, b, and c are constants.

4.

FLASHCARD QUESTION

Front

How do you convert a quadratic function from vertex form to standard form?

Back

To convert from vertex form y = a(x-h)² + k to standard form, expand the equation to the form y = ax² + bx + c.

5.

FLASHCARD QUESTION

Front

What is the significance of the x-intercepts of a quadratic function?

Back

The x-intercepts of a quadratic function are the points where the graph intersects the x-axis, indicating the values of x for which y = 0.

6.

FLASHCARD QUESTION

Front

How do you determine the maximum height of a projectile modeled by a quadratic function?

Back

The maximum height of a projectile can be found by determining the vertex of the quadratic function, which occurs at t = -b/(2a) for the function h(t) = at² + bt + c.

7.

FLASHCARD QUESTION

Front

What is the formula to find the vertex of a quadratic function given in standard form?

Back

The vertex (h, k) of a quadratic function in standard form f(x) = ax² + bx + c can be found using h = -b/(2a) and k = f(h).
