Question

Write a function rule for “the output is half of the input.”

Answer 1

Given : The output is half of the input

Lets input be $\mathrm{x}$ and output be $\mathrm{y}$

So, according to given condition,

$\mathrm{y}=\frac{\mathrm{x}}{2}$

Hence, a function rule for the output is half of the input is $\mathrm{y}=\frac{\mathrm{x}}{2}$.
