Front

What is the initial value when Tim buys a new phone for $125 and pays $50 per month?

Back

The initial value is $125.

Front

Is the mapping a function if each input has exactly one output?

Back

Yes, it is a function.

Front

Which of the following graphs are linear? Select all that apply: 1, 2, 3, 4, 5.

Back

Graph 2 is linear.

Front

What is the domain of the relation represented by the ordered pairs {(-4,1), (-2,3), (0,5), (2,7), (4,9)}?

Back

The domain is {-4,-2,0,2,4}.

Front

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

Back

No, it is not a function because the input '1' has two different outputs.

Front

Define a function in mathematical terms.

Back

A function is a relation where each input has exactly one output.

Front

What is the range of a function?

Back

The range is the set of all possible outputs of a function.

Front

What does it mean for a graph to be linear?

Back

A linear graph is a straight line that represents a linear relationship between variables.

Front

How do you determine if a relation is a function using a mapping diagram?

Back

If any input is connected to more than one output, it is not a function.

Front

What is the difference between domain and range?

Back

Domain is the set of all possible inputs, while range is the set of all possible outputs.
