Question

question
fill in the blanks below in order to justify whether or not the mapping shown represents a function.
set a
set b
answer attempt 1 out of 3
the mapping diagram above represents
a function since there is one number
in set a (the input)
where there
are multiple mappings to set b (the output)

Explanation:

Step1: Recall function definition

A function is a mapping where each input has exactly one output.

Step2: Analyze the mapping

Look at Set A (inputs): 8 maps to both 3 and -1.

Step3: Conclude if it's a function

Since one input has two outputs, it is not a function.

Answer:

The mapping diagram above represents not a function since there is one number 8 in Set A (the input) where there are multiple mappings from one input to Set B (the output).
