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

Back

A quadratic function can have a maximum or minimum value depending on the direction of its parabola. If the parabola opens upwards, it has a minimum value; if it opens downwards, it has a maximum value.

How do you find the slope between two points?

Back

The slope (m) between two points (x1, y1) and (x2, y2) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

Given the ordered pairs (-2, -1) and (-4, -7), what is the slope?

Front

What is the domain of a relation?

Back

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

Front

Identify the domain of the relation: (-6,14), (0,32), (2,38), (4,44).

Back

The domain is {-6, 0, 2, 4}.

What does it mean for a statement to be true or false in mathematics?

Back

A true statement accurately reflects a mathematical fact, while a false statement does not.

Front

What is the y-intercept of a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of y when x = 0.

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

Back

A function is increasing if its output values rise as the input values increase, and decreasing if its output values fall as the input values increase.
