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

How do you determine the domain from a graph?

Back

To determine the domain from a graph, identify the x-values that correspond to points on the graph.

Front

What is an arithmetic sequence?

Back

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is constant.

Front

What is a geometric sequence?

Back

A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio.

Front

What is the common ratio in a geometric sequence?

Back

The common ratio is the factor by which we multiply to get from one term to the next in a geometric sequence.

Front

What is a linear function?

Back

Front

How do you find the solution to a linear function from a graph?

Back

The solution to a linear function from a graph is the y-value corresponding to a given x-value on the line.

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, or equal to the other.

Front

How do you graph an inequality?

Back

To graph an inequality, first graph the corresponding equation as if it were an equality, then use a dashed line for < or > and a solid line for ≤ or ≥. Shade the appropriate region.

Front

What is factorization in algebra?

Back

Factorization is the process of breaking down an expression into a product of simpler expressions or factors.
