tangent y=x^2+4x-11,(2,-1)

Lösung

tangente von

y = x^{2} + 4 x - 11, (2, - 1)

Lösung

y = (8 - 22) x + 42 - 17 or y = (22 + 8) x - 17 - 42

Schritte zur Lösung

Steigung der Tangente an

(2, - 1) : m = \frac{x ^{2} + 4 x - 10}{x - 2}

Finde die Steigung von

y = x^{2} + 4 x - 11 : m = 2 x + 4

Löse

2 x + 4 = \frac{x ^{2} + 4 x - 10}{x - 2} : x = 2 - 2, x = 2 + 2

Finde die Tangente an

x = 2 - 2 : y = (8 - 22) x + 42 - 17

Finde die Tangente an

x = 2 + 2 : y = (22 + 8) x - 17 - 42

y = (8 - 22) x + 42 - 17 or y = (22 + 8) x - 17 - 42
