Front

What is a function's maximum point?

Back

The highest point on the graph of a function where the function value is greater than all nearby points.

Front

What is a function's minimum point?

Back

The lowest point on the graph of a function where the function value is less than all nearby points.

Front

How do you find the x-intercept of a function?

Back

Set the function equal to zero and solve for x.

Front

How do you find the y-intercept of a function?

Back

Set x equal to zero and solve for the function.

Front

What does it mean for a function to be positive?

Back

The function's values are greater than zero in a given interval.

Front

What does it mean for a function to be negative?

Back

The function's values are less than zero in a given interval.

Front

What is the significance of x-intercepts?

Back

They indicate the points where the graph crosses the x-axis.

Front

What is the significance of y-intercepts?

Back

They indicate the points where the graph crosses the y-axis.

Front

What is the domain of a function?

Back

The set of all possible input values (x-values) for the function.

Front

What is the range of a function?

Back

The set of all possible output values (y-values) for the function.
