Unit 3 Review-Alg 1 (For Final)

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 relation is defined.

Front

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

Back

{-6, 0, 2, 4}

Front

What is a common difference in an arithmetic sequence?

Back

The common difference is the constant amount that each term in the sequence increases or decreases by.

Front

Find the common difference of the sequence: -34, -29, -24, -19, ...

Back

d = 5

Front

What is the vertical line test?

Back

The vertical line test is a method to determine if a graph represents a function. If a vertical line intersects the graph at more than one point, it is not a function.

Front

Does the graph represent a function if it fails the vertical line test?

Back

No, because the vertical line test shows there are repeating input values.

Front

What is the range of a relation?

Back

The range of a relation is the set of all possible output values (y-values) that correspond to the domain.

Front

Identify the range of the relation: {(-6,14), (0,32), (2,38), (4,44)}

Back

{14, 32, 38, 44}

Front

What is a function?

Back

A function is a relation where each input value (x) is associated with exactly one output value (y).

Front

Is the relation {(1,2), (1,3)} a function?

Back

No, because the input value 1 is associated with two different output values.
