Analyse continuity and differentiability at joins - visual asymptote link
At the join \(x=2\), the left branch value is 2 and the right branch parameter is \(k\). Enter \(k\) for continuity.
Worked practice: result and interpretation
Calculate the requested result first, then choose the interpretation that follows from it.
