Question

What is the input value for the following function if the output value is 5?y = x - 315852

Answer 1

Solution:

Given the function below

$y=x-3$

Where

$\begin{gathered} y\text{ is the output value} \\ x\text{ is the input value} \end{gathered}$

If the output value is 5, the input value will be

$\begin{gathered} y=x-3 \\ Where,\text{ y}=5 \\ 5=x-3 \\ Collect\text{ like terms} \\ x=5+3=8 \\ x=8 \end{gathered}$

Hence, the input value is 8
