tangent of f(x)=x^3-15x,(1,-14)

tangent of

f (x) = x^{3} - 15 x, (1, - 14)

y = - 12 x - 2

Solution steps

Find the slope of

f (x) = x^{3} - 15 x : \frac{df ( x )}{d x} = 3 x^{2} - 15

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 = - 12

Find the line with slope m=

- 12

and passing through

(1, - 14) : y = - 12 x - 2

y = - 12 x - 2
