Continuity Checker
f(x) = p₁x + q₁ for x < a, and f(x) = p₂x + q₂ for x ≥ a
How This Is Calculated
A function is continuous at a point only when three things all agree: the left-hand limit, the right-hand limit, and the function's actual value there. For a piecewise-linear function, this reduces to comparing where each piece evaluates at the break point. See the full definition and worked examples in the 2nd PUC exam analysis, which covers Continuity & Differentiability as a high-weightage chapter.
