Exploring Domain and Range of Functions

What is the domain of a function?

• The set of output values

• The set of input values

• The set of all possible z-values

• The set of all possible y-values

How do you write the domain for ordered pairs?

• List all x-values

• List all y-values

• List all w-values

• List all z-values

In a mapping diagram, what do the arrows represent?

• Connections between inputs and outputs

• Connections between outputs and inputs

• Connections between y-values and w-values

• Connections between x-values and z-values

In a word problem, if Laura can make between 0 and 1000 cookies, how would you write the domain?

• 0 ≤ c ≤ 1000

• 0 < c < 1000

• 0 ≤ c < 1000

• 0 < c ≤ 1000

If Laura makes 0 cookies, how much money does she make?

• $0

• $50

• $500

• $1000

What is a discrete graph?

• A graph with connected points

• A graph with unconnected points

• A graph with continuous lines

• A graph with no points

How do you write the domain for a continuous graph?

• As a list of z-values

• As inequalities

• As a list of y-values

• As a list of x-values

What does an open dot on a graph indicate?

• The value is not included

• The value is included

• The value is infinite

• The value is zero

What is a discontinuous graph?

• A graph with connected points

• A graph with a hole or break

• A graph with continuous lines

• A graph with no points

How do you handle exceptions in domain and range for graphs?

• Include them in the range

• Write them as inequalities

• List them as exceptions

• Ignore them
