Check model domain restrictions - depth scenario

Check the modelling or algorithm condition first. A library system model is valid on \(0\le x\le 19\). State 1 if \(x=8\) is inside the domain, otherwise 0. Enter the requested value and choose the interpretation that matches the result.

Worked practice: result and interpretation

Calculate the requested result first, then choose the interpretation that follows from it.
