Question

Write a function rule for “the output is eight more than one-seventh of the input.”

Answer 1

Given ,the output is eight more than one-seventh of the input.

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

So, according to given condition,

$\mathrm{y}=8+\frac{1}{7}\mathrm{x}$

Hence, a function rule for the output is eight more than one-seventh of the input is, $\mathrm{y}=8+\frac{1}{7}\mathrm{x}$.
