Front

What is a nonlinear function?

Back

A nonlinear function is a function that does not graph to a straight line. Its rate of change varies and can be represented by equations such as quadratics, exponentials, etc.

Front

What is a function?

Back

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

Front

Is the relation {(1,5),(1,7),(3,9),(4,11)} a function?

Back

No, because the input 1 has two different outputs (5 and 7).

Front

What is the rate of change?

Back

The rate of change is a measure of how much a quantity changes in relation to another quantity, often represented as the slope in a linear function.

Front

If Brian's rate of change is 30, what does this mean?

Back

It means that for every unit increase in the independent variable, the dependent variable increases by 30 units.
