📋 Introduction (Pretest)

Diagnostic: 15 problems covering the whole limits unit. Work them in order — the early ones are foundational, the later ones are capstone. If you can do all 15, you're ready for the posttest.

Problems

• Q1 — Secant slope of a parabola
• Q2 — Limit at infinity, top wins
• Q3 — Limit at infinity, bottom wins
• Q4 — Continuity & discontinuity
• Q5 — One-sided limits, jump
• Q6 — Derivatives, power rule
• Q7 — Secant slope of a cubic
• Q8 — Removable discontinuity
• Q9 — One-sided limit of a piecewise function
• Q10 — Indeterminate, factor and cancel
• Q11 — One-sided limit at a vertical asymptote
• Q12 — General difference quotient
• Q13 — Match: hole, jump, vertical asymptote
• Q14 — Indeterminate, factor and cancel, negative root
• Q15 — Slope of the tangent line (capstone)
