Features of Functions

Front

What is the y-intercept?

Back

The y-intercept is the point where a graph crosses the y-axis. It is represented as (0, y).

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

What is the minimum value of a function?

Back

The minimum value of a function is the lowest point on the graph of the function.

Front

What does it mean for a graph to be constant on an interval?

Back

A graph is constant on an interval if it does not change in value over that interval.

Front

How do you find the y-intercept from a function's equation?

Back

To find the y-intercept, set x = 0 in the function's equation and solve for y.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) that the function can accept.

Front

What is a function's increasing interval?

Back

An increasing interval is where the function's output values (y-values) rise as the input values (x-values) increase.

Front

What is a function's decreasing interval?

Back

A decreasing interval is where the function's output values (y-values) fall as the input values (x-values) increase.

Front

What is a local maximum?

Back

A local maximum is a point on the graph where the function value is higher than all nearby points.

Front

What is a local minimum?

Back

A local minimum is a point on the graph where the function value is lower than all nearby points.
