Piecewise Functions

Front

What is a piecewise function?

Back

A piecewise function is a function that is defined by different expressions or formulas over different intervals of its domain.

How do you determine the domain of a piecewise function?

Back

To determine the domain of a piecewise function, identify the intervals for which each piece of the function is defined and combine them.

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 find the range of a piecewise function?

Back

To find the range of a piecewise function, evaluate each piece over its domain and combine the resulting output values.

Front

What does it mean for a function to behave like a quadratic function?

Back

A function behaves like a quadratic function if it can be represented by a polynomial of degree 2, typically having a parabolic shape.

Front

What is the significance of domain restrictions in piecewise functions?

Back

Domain restrictions indicate the specific values of x for which the function is defined, which can affect the overall behavior and output of the function.

How do you match a graph to its corresponding piecewise function?

Back

To match a graph to its corresponding piecewise function, analyze the shape and behavior of the graph in different intervals and compare it to the equations of the piecewise function.

What is the importance of understanding intervals in piecewise functions?

Back

Understanding intervals is crucial because each interval may have a different rule or equation that defines the function's behavior.

What is the notation for representing intervals in mathematics?

Back

Intervals are often represented using brackets [ ] for inclusive endpoints and parentheses ( ) for exclusive endpoints.

How do you express the domain of a piecewise function using interval notation?

Back

The domain can be expressed in interval notation by combining the intervals for which the function is defined, using union symbols as needed.
