In dieser Aufgabe ${\\simplify[std,!collectLikeFractions]{ f(x) = ({a[2]}x ^ {n[2]}) + ({a[1]}x^{n[1]}) + ({a[0]}x^{n[0]}) } }$ sind die einzelnen Ableitungen:

Die Ableitung einer Potenzfunktionen wird gebildet mit

\n

\\[ f(x) = x^n \\Rightarrow f'(x) = n \\cdot x^{n-1}  \\]

Mit der Faktorregel

\n

\\[ f(x) = a \\cdot g(x) \\Rightarrow f'(x) = a \\cdot g'(x) \\]

\n

und der Summenregel

\n

\\[ f(x) =  g(x) + h(x) \\Rightarrow f'(x) = g'(x) + h'(x)\\]

können Linearkombinationen von Funktionen abgeleitet werden, also auch Polynomfunktionen.
