Interpret phase-line stability - context check
A phase line for a traffic authority model has arrows pointing toward equilibrium \(E\) from both sides: left test value -3 gives a positive rate and right test value 6 gives a negative rate. Enter 1 if \(E\) is stable, 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.
