Determining Function or Nonfunction
The domain is x and the range is y
-Do x values repeat?
-Are the x values numerical order?
-Is the input on top or left? Is the output on bottom or right?
The domain is a/x and the range is b/y
-Are the arrows going in the same directions?
-Are the x and y values in numerical order?
-Is there a structure?
-Are there repeating numbers in the
The domain is x and the range is y (x,y)
-Are there parenthesis and commas?
The domain x and the range is y
-Are there arrows on the line?
-Are the x and y axis' labeled and labeled in the right spot (top or bottom/left or right)?
-Are the numbers on the left of the y-axis and bottom of the x-axis?
-Are the increments equal?
Domain and Range
Obviously the domain is D and the range is R
- Are the domain and range labeled?
-Are the the domain and range in numerical order? Any repeating numbers?
- Are there set brackets?
Translating Domain and Range
-It moves because you are adding and subtracting from the domain or range values, causing the points to move around the graph
-If you know what the domain and range are for a map, ordered pair, table, and graph then you can easily manipulate any function from one to another.
-You just plug the x and y where they would logically be in the table (for example).
