Final Review Part-1 ( solving equations & DR)

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

How do you represent the domain of a function graphically?

Back

The domain can be represented on a number line, showing the range of x-values that the function can take.

Front

What does the notation -5 ≤ x ≤ 3 mean?

Back

This notation indicates that x can take any value from -5 to 3, inclusive.

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 do you find the domain from a graph?

Back

To find the domain from a graph, identify the x-values that the graph covers.

Front

What is a discrete function?

Back

A discrete function is one that has distinct, separate values, often represented by individual points on a graph.

Front

What is a continuous function?

Back

A continuous function is one that has no breaks, jumps, or holes in its graph, meaning it can take any value within a given interval.

Front

How do you write the domain and range from a set of points?

Back

The domain is the set of all x-values from the points, and the range is the set of all y-values.

Front

What does the notation x ≥ -3 signify?

Back

This notation means that x can take any value greater than or equal to -3.

Front

What is the difference between open and closed intervals?

Back

Open intervals do not include endpoints (e.g., (a, b)), while closed intervals do include endpoints (e.g., [a, b]).
