Interpreting Graphs of Functions

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

How do you determine the range from a graph?

Back

To determine the range from a graph, identify the lowest and highest points on the y-axis that the graph reaches.

Front

What is an absolute maximum of a function?

Back

The absolute maximum is the highest point on the graph of the function over its entire domain.

Front

How do you find the absolute maximum from a graph?

Back

Look for the highest point on the graph; the coordinates of this point represent the absolute maximum.

Front

What is a y-intercept?

Back

The y-intercept is the point where the graph of a function crosses the y-axis.

Front

How can you find the y-intercept from a graph?

Back

The y-intercept can be found by looking at the point where the graph intersects the y-axis.

Front

What are x-intercepts?

Back

X-intercepts are the points where the graph of a function crosses the x-axis.

Front

How do you find x-intercepts from a graph?

Back

Identify the points where the graph intersects the x-axis; these points have a y-value of 0.

Front

What is a minimum of a function?

Back

The minimum of a function is the lowest point on the graph of the function over its entire domain.

Front

How do you find the minimum from a graph?

Back

Look for the lowest point on the graph; the coordinates of this point represent the minimum.
