Key Features of Functions Explored

This video tutorial covers key features of functions, including domain, range, maximum and minimum points, intercepts, intervals of increase, decrease, and constant, as well as end behavior. It explains how to identify these features on a graph and use interval notation. The video also introduces the concept of extrema and relative extrema, providing a comprehensive understanding of graph analysis.

What is the domain of a function?

• All possible values of y

• All possible values of x

• The highest point on the graph

• The lowest point on the graph

Where does the domain of the given graph start?

• At x = 4

• At x = 2

• At x = 0

• At x = -2

What is the range of a function?

• All possible values of x

• All possible values of y

• The highest point on the graph

• The lowest point on the graph

Where does the range of the given graph start?

• At y = 0

• At y = 1

• At y = 4

• At y = 2

What is the maximum value of the given graph?

• 1

• 2

• 3

• 4

What is the minimum value of the given graph?

• 4

• 2

• 1

• 3

What is an x-intercept?

• The lowest point on the graph

• The highest point on the graph

• A point where the graph touches the x-axis

• A point where the graph touches the y-axis

What is a y-intercept?

• A point where the graph touches the y-axis

• The lowest point on the graph

• A point where the graph touches the x-axis

• The highest point on the graph

What does it mean if a function is increasing?

• The function is moving upwards

• The function is moving downwards

• The function is constant

• The function is at its maximum

What is end behavior in a graph?

• The behavior of the graph as x approaches infinity or negative infinity

• The behavior of the graph at its minimum point

• The behavior of the graph at its maximum point

• The behavior of the graph at its intercepts
