Answer 1

B. The relation is not a function. Some of the input values are paired with

more than one output value.

Explanation

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Step 1

Identify the input values and compare with the outputs

as we can see one input is related to TWO outputs, for example

$\begin{gathered} 1.7\rightarrow80 \\ 1.7\rightarrow79 \end{gathered}$

hence, the relation is not a function

B. The relation is not a function. Some of the input values are paired with

more than one output value.
