What is a Venn diagram?

Back

A Venn diagram is a visual representation of the relationships between different sets. It uses overlapping circles to show how the sets intersect.

How do you determine if a mapping is a function?

Back

A mapping is a function if each input (x-value) is associated with exactly one output (y-value). If any input is associated with more than one output, it is not a function.

What is the solution to the equation f - 4 = 6f + 26?

Back

f = -6.

Front

How do you order numbers from least to greatest?

Back

To order numbers from least to greatest, compare their values and arrange them in ascending order. For example, √23, 5, 6, 43% is ordered as 43%, √23, 5, 6.

What is the definition of 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

What does it mean for a table to represent a function?

Back

A table represents a function if each input value corresponds to one and only one output value.

Front

What is the difference between rational and irrational numbers?

Back

Rational numbers can be expressed as fractions, while irrational numbers cannot be expressed as fractions and have non-repeating, non-terminating decimals.
