tangent of y=x^3-12x,(1,-11)

tangent

y = - 9 x - 2

Solution steps

Find the slope of

y = x^{3} - 12 x : \frac{d y}{d x} = 3 x^{2} - 12

EN : T i tl e G e n er a l Eq u a t i o n Sl o p e A t P o in t 2 Eq : m = - 9

Find the line with slope m=

- 9

and passing through

(1, - 11) : y = - 9 x - 2

y = - 9 x - 2
