FLASHCARD QUESTION

Front

What is the vertex of a quadratic function?

Back

The vertex is the highest or lowest point of the parabola, depending on its orientation. It is represented as a coordinate point (h, k) in the vertex form of a quadratic function: y = a(x - h)² + k.

FLASHCARD QUESTION

Front

What are x-intercepts in a quadratic function?

Back

X-intercepts are the points where the graph of the quadratic function crosses the x-axis. They are the solutions to the equation when y = 0.

FLASHCARD QUESTION

Front

How do you find the vertex from a graph of a quadratic function?

Back

The vertex can be identified as the point where the parabola changes direction, which is the highest or lowest point on the graph.

4.

FLASHCARD QUESTION

Front

What is the y-intercept of a quadratic function?

Back

The y-intercept is the point where the graph crosses the y-axis, represented as (0, k) where k is the value of the function when x = 0.

FLASHCARD QUESTION

Front

How many solutions can a quadratic function have?

Back

A quadratic function can have zero, one, or two solutions, depending on the number of times the graph intersects the x-axis.

6.

FLASHCARD QUESTION

Front

What is the standard form of a quadratic function?

Back

The standard form of a quadratic function is given by the equation: y = ax² + bx + c, where a, b, and c are constants.

7.

FLASHCARD QUESTION

Front

What does the 'a' value in a quadratic function indicate?

Back

The 'a' value determines the direction of the parabola (upward if a > 0, downward if a < 0) and affects the width of the parabola.
