Unit 3: Key Features of Functions Practice

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

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 a y-intercept?

Back

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

Front

What is an x-intercept?

Back

The x-intercept is the point where the graph of a function crosses the x-axis, represented as (x, 0).

Front

What does it mean for a function to be increasing?

Back

A function is increasing on an interval if, as x increases, the value of f(x) also increases.

Front

What does it mean for a function to be decreasing?

Back

A function is decreasing on an interval if, as x increases, the value of f(x) decreases.

Front

What is a minimum point of a function?

Back

A minimum point is the lowest point on the graph of a function within a given interval.

Front

What is a maximum point of a function?

Back

A maximum point is the highest point on the graph of a function within a given interval.

Front

What is an interval in the context of functions?

Back

An interval is a range of x-values over which a function is analyzed.

Front

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

Back

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