Key Features and Notation

Front

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

Back

The equation for the axis of symmetry is x = h, where (h, k) is the vertex of the parabola.

Front

What is the mathematical notation for the interval -8 ≤ x < 9?

Back

The mathematical notation is [-8, 9).

Front

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

Back

The vertex can be found using the formula (h, k) where h = -b/(2a) and k = f(h).

Front

What does the term 'decreasing interval' refer to in a linear function?

Back

A decreasing interval refers to the range of x-values over which the function's output decreases as x increases.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

How can you determine if a function is increasing or decreasing?

Back

A function is increasing if its graph rises as you move from left to right, and decreasing if it falls.

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 its orientation.

Front

What does it mean for a function to have a domain of all real numbers greater than 7?

Back

It means that the function is defined for all x-values greater than 7, not including 7 itself.

Front

What is the standard form of a quadratic function?

Back

The standard form of a quadratic function is f(x) = ax^2 + bx + c.
