Across
  1. 2. = Shows intervals of increase and decrease, the ups and downs of love.
  2. 5. = When limits from left and right don’t match, love is complicated.
  3. 7. = Like true love, exists from both sides and agrees.
  4. 9. = A sharp point where the derivative does not exist, love hurts.
  5. 10. = The point where love (and a curve) changes its mood from up to down.
Down
  1. 1. = This tells whether a function is rising or falling, just like feelings.
  2. 3. = The derivative equals zero here, love pauses for a moment.
  3. 4. = Used to study where a function is positive or negative, love or heartbreak.
  4. 6. = When the second derivative is positive, the graph smiles, like being in love.
  5. 8. = A value the function approaches but never quite reaches, like a crush.
