Answer:
domain is {-2,2,3,4}
Step-by-step explanation:
In a mapping diagram , the input x is the domain and output (y) is the range
In the given mapping diagram, the input are the first values that gives the output (second values)
The set of x values in the diagram is -2, 3, 4 and 2
The set of x values are the domain of the function. Write the domain in order.
So domain is {-2,2,3,4}
