06. Parameter matching for piecewise differentiability – Practice Quiz

Match values and finite one-sided slopes at a piecewise join. Solve for parameters, distinguish no solution from nonunique solutions, and verify the result with the original difference quotients. Prerequisites: continuity, elementary derivatives and differentiability failures.
