tangent of y=4x^3-2x,(1,2)

tangent of

y = 4 x^{3} - 2 x, (1, 2)

y = 10 x - 8

Solution steps

Find the slope of

y = 4 x^{3} - 2 x : \frac{d y}{d x} = 12 x^{2} - 2

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 = 10

Find the line with slope m=

10

and passing through

(1, 2) : y = 10 x - 8

y = 10 x - 8
