How does this quiz work?
Read each question, choose one answer among A, B, C and D, then check it: a short explanation appears after every answer. Your score out of 10 is shown at the end, and you can restart the quiz as often as you like.
What should you review before the quiz?
Reread the key facts of the lesson and the worked example. If a question is hard, go back to the matching part of the lesson, then try the quiz again. Write your work on scrap paper: most mistakes come from skipping a step, not from the idea itself.
Remember:
Chain rule: outer derivative evaluated at the inside, times the inner derivative.
Implicit differentiation: every y-term gets a factor of dy/dx from the chain rule.
Inverse functions: if f(a) = b, then (f⁻¹)′(b) = 1/f′(a).
The second derivative f″ is the derivative of f′ and measures how the slope changes.
