What is a function?

Back

A function is a relation that assigns exactly one output for each input. It can be represented as an equation, a graph, or a table.

What is the slope of a linear function?

Back

The slope of a linear function is the rate of change of the function, calculated as the change in y divided by the change in x (rise/run).

What is the y-intercept of a function?

Back

The y-intercept is the point where the graph of a function crosses the y-axis, represented by the value of y when x = 0.

How do you determine if a function is increasing or decreasing?

Back

A function is increasing if the output values rise as the input values increase, and decreasing if the output values fall as the input values increase.

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 curves.

What is the difference between a linear increasing function and a linear decreasing function?

Back

A linear increasing function has a positive slope (rises from left to right), while a linear decreasing function has a negative slope (falls from left to right).

What does it mean for a function to be increasing?

Back

A function is increasing if, for any two points in its domain, if the first point has a smaller x-value than the second, the first point will have a smaller y-value.

Front

What is a graph?

Back

A graph is a visual representation of a function, showing the relationship between the input (x-axis) and output (y-axis) values.
