Front

Does this graph represent a proportional relationship?

Back

Yes, a proportional relationship is one where the ratio between two variables is constant.

Front

Is this graph a function or not a function?

Back

Not a Function, a relation is not a function if any vertical line intersects the graph at more than one point.

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant ratio between two proportional quantities, in this case, it is 15.

Front

This line has a __________ slope.

Back

Positive, a positive slope indicates that as one variable increases, the other variable also increases.

Front

What is the range of the mapping?

Back

The range is the set of output values, in this case, {1, 2, 4}.

Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where their ratio is constant.

Front

Define a function.

Back

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

Front

What does a negative slope indicate?

Back

A negative slope indicates that as one variable increases, the other variable decreases.

Front

What is the domain of a function?

Back

The domain is the set of all possible input values (x-values) for a function.

Front

What is the difference between linear and nonlinear functions?

Back

Linear functions create straight lines when graphed, while nonlinear functions create curves.
