What is a linear function?

Front

What does it mean for a function to be increasing?

Back

A function is increasing on an interval if, as the input values (x) increase, the output values (y) also increase.

Front

What does it mean for a function to be decreasing?

Back

A function is decreasing on an interval if, as the input values (x) increase, the output values (y) decrease.

Front

What is a nonlinear function?

Back

A nonlinear function is a function that does not graph to a straight line. Examples include quadratic functions, exponential functions, and square root functions.

Front

How do you determine the slope of a line given two points?

Back

Front

What is the y-intercept of a line?

Back

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input (x) has exactly one output (y). A relation can have multiple outputs for a single input.

Front

What is a table of values in relation to functions?

Back

A table of values lists pairs of input (x) and output (y) values, showing how the function behaves for different inputs.

Front

What does it mean for a relationship to be nonlinear in a table of values?

Back

A nonlinear relationship in a table of values means that the change in y is not consistent as x changes, indicating a curve or a non-straight line when graphed.

Front

How can you identify if a function is increasing or decreasing from a graph?

Back

If the graph rises as you move from left to right, the function is increasing. If it falls, the function is decreasing.
