What is a function in mathematics?

Back

A function is a relation that assigns exactly one output for each input. It can be represented as a set of ordered pairs, a graph, or an equation.

Front

How can you determine if a graph represents a function?

Back

A graph represents a function if any vertical line drawn through the graph intersects it at most once (Vertical Line Test).

Front

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean to order numbers from least to greatest?

Back

Ordering numbers from least to greatest means arranging them in ascending order, starting with the smallest number and ending with the largest.

Front

What are the subsets of real numbers?

Back

The subsets of real numbers include natural numbers, whole numbers, integers, rational numbers, and irrational numbers.

Front

What is a Venn diagram?

Back

A Venn diagram is a visual representation used to show the relationships between different sets, often using overlapping circles.

Front

How do you find the coordinates of a transformed triangle on a coordinate plane?

Back

To find the coordinates of a transformed triangle, apply the transformation rules (such as translation, rotation, or reflection) to each vertex of the triangle.

Front

What is the purpose of writing an equation from a table of values?

Back

Writing an equation from a table of values helps to express the relationship between the variables in a mathematical form, allowing for predictions and analysis.

Front

What is the difference between rational and irrational numbers?

Back

Rational numbers can be expressed as a fraction of two integers, while irrational numbers cannot be expressed as a simple fraction and have non-repeating, non-terminating decimal expansions.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise (change in y) over the run (change in x).
