tangent f(x)=2x^2+2x,(-2,-6)

Lösung

tangente von

f (x) = 2 x^{2} + 2 x, (- 2, - 6)

Lösung

y = 2 (25 - 3) x + 85 - 18 or y = - 2 (25 + 3) x - 18 - 85

Schritte zur Lösung

Steigung der Tangente an

(- 2, - 6) : m = \frac{2 x ^{2} + 2 x + 6}{x + 2}

Finde die Steigung von

f (x) = 2 x^{2} + 2 x : m = 4 x + 2

Löse

4 x + 2 = \frac{2 x ^{2} + 2 x + 6}{x + 2} : x = - 2 + 5, x = - 2 - 5

Finde die Tangente an

x = - 2 + 5 : y = 2 (25 - 3) x + 85 - 18

Finde die Tangente an

x = - 2 - 5 : y = - 2 (25 + 3) x - 18 - 85

y = 2 (25 - 3) x + 85 - 18 or y = - 2 (25 + 3) x - 18 - 85
