Unit 2 Test Review

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

How can you determine if a relation is a function?

Back

A relation is a function if every x value has exactly one corresponding y value.

Front

What does it mean for a statement to be true in the context of functions?

Back

A statement is true if it accurately describes the properties or behavior of functions and their relations.

Front

What is the significance of the statement 'the domain of a relation is the set of all input values'?

Back

This statement emphasizes that the domain includes every x-value that can be used in the relation.

Front

How do you evaluate a function at a specific point, such as g(-2)?

Back

To evaluate a function at a specific point, substitute the input value into the function's equation and simplify.

Front

What is the notation used to represent a function?

Back

Functions are typically represented using notation such as f(x), g(x), etc., where 'f' or 'g' denotes the function and 'x' is the input variable.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input is associated with exactly one output, while a relation can have multiple outputs for a single input.

Front

What does the notation f(9) = 8 indicate?

Back

The notation f(9) = 8 indicates that when the input value is 9, the output value of the function f is 8.

Front

What is a vertical line test?

Back

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