tangent of y=x^3-5x,(-1,4)

tangent of

y = x^{3} - 5 x, (- 1, 4)

y = - 2 x + 2

Solution steps

Find the slope of

y = x^{3} - 5 x : \frac{d y}{d x} = 3 x^{2} - 5

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 = - 2

Find the line with slope m=

- 2

and passing through

(- 1, 4) : y = - 2 x + 2

y = - 2 x + 2
