4.1 Domain and Range of a function

I can identify the domain and range of a function from a graph and table of values.

Dec 13­2:13 PM

Function- a relationship that pairs each input (x) with exactly one output (y).Domain- the set of all possible input values (x).Range- the set of all possible output values (y).

Given the set of coordinates: (3,6), (4,8), (5,10), (6, 12), ( 7, 14)

What is the domain? 

What is the range?

Finding Domain and Range from a GraphFind the domain and range of the function represented by the graph.First, write the ordered pairs and identify the inputs (x)

and outputs (y).

An equation is in function form if it is solved for y.

not in function form in function form

x + y = 1 y = -x + 1Are the following are in function form? 

1. y = 3x + 9 2. 3x + 7y = 9

3. 5y = 3x + 1 4. y = (1/2)x

Finding the Range of a FunctionThe domain of the function represented by 2x + y = 8 is -2, 0, 2, 4, and 6. What is the range of the function represented by the table?

First, write the equation in function form.

Second, use the function form to make an input-output table.

Third, write the range.

The table shows the percent y (in decimal form) of the moon that was visible at midnight x days after January 24, 2011.

a. Interpret the domain and range.

b. What percent of the moon was visible on January 26, 2011?

Remember: Interpret means to tell what it is in the story.
