Question

Write a function rule for “the output is one more than twice the input.”

Answer 1

Given : The output is one more than twice the input

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

So, according to given condition,

$\mathrm{y}=1+2\mathrm{x}$

Hence, a function rule for the output is one more than twice the input is $\mathrm{y}=1+2\mathrm{x}$.
