Refer to the mapping diagram below to answer questions 1 – 4
X
Y
1) Create a rough sketch/scatterplot of the mapping diagram. Be sure to label all ordered pairs
2) Does this represent a function? How can you tell by looking at the graph? How could you tell by only looking at
the mapping diagram?
3) What is the domain? What is the range?
Domain =
Range =
4) Which statement best describe this diagram
a. It is a relation, but not a function
b. It is both a relation and a function
c. It is not a relation, but it is a function
d. It is neither a relation, nor a function
Refer to the graph shown to answer questions 5 – 8
5) Which statements best describe this graph? Circle
all true answers
a. The domain is [-1, 1]
b. The domain is [0,1]
c. The range is [-1, 1]
d. The range is [0, 1]
e. The graph is increasing from (-1, -0.5) and
from (-0.5, 0)
f. The graph is decreasing from (0, 0.5) and
from (0.5, 1)
g. The graph is increasing more steeply from
(-1, -0.5) than it is from (-0.5, 0)
h. The graph is continuous
i. This graph is both a function and a relation
j. This graph is a relation, but not a function
