Essentials of Alg 2: Common Assessment Review Unit 1

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

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

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

Back

A graph represents a function if every x-value has exactly one corresponding y-value, which can be tested using the vertical line test.

Front

What is an increasing interval in a graph?

Back

An increasing interval is a section of the graph where the y-values rise as the x-values increase.

Front

What is a decreasing interval in a graph?

Back

A decreasing interval is a section of the graph where the y-values fall as the x-values increase.

Front

What is a constant interval in a graph?

Back

A constant interval is a section of the graph where the y-values remain the same as the x-values change.

Front

How do you find f(2) from a graph?

Back

To find f(2), locate the point on the graph where x=2 and read the corresponding y-value.
