Q

Wie leitet sich f(x) einmal ab?
f(x) = x³ + 7

A

f’(x) = 3x²

xⁿ → n• xⁿ-¹

Q

Was Zeigen die erste und die zweite Ableitung von f(x)?

A

f’(x) zeig die Steigung von f(x),

f’‘(x) zeigt die Krümmung von f(x) und die Steigung von f’(x)

Krümmung → wie stark hält man das Lenkrad?

Q

Was gilt bei bei Ableitung einer Funktion bezüglich des Hoch/Tiefpunkts und den Wendepunkten?

A
  • f(x) Hoch/Tiefpunkt → f’(x) Nullstelle
  • f(x) Wendepunkt → f’(x) Hoch/Tiefpunkt

Q

Bilde f(n) = b * aⁿ für
→ Bakterien Kultur besteht aus 200, und verdreifacht sich jede Stunde

A
  • f(n) = b * aⁿ
  • → f(n) = 200 * 3ⁿ
