Front

What is a nonlinear function?

Back

A nonlinear function is a function that does not form a straight line when graphed. Its rate of change is not constant, and it can include quadratic, exponential, and other types of functions.

Front

How do you evaluate a function at a specific point?

Back

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

Front

What is the range of a set of ordered pairs?

Back

The range of a set of ordered pairs is the set of all second elements (y-values) from each ordered pair.

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 does it mean for a function to be defined?

Back

A function is defined for a particular input if there is a corresponding output value. If no output exists for an input, the function is undefined at that point.

What is the slope-intercept form of a linear equation?

Back

Front

How can you determine if a function is linear or nonlinear from its graph?

Back

A function is linear if its graph is a straight line. If the graph curves or has bends, it is nonlinear.
