tangent of f(x)=2x^3-4x+6

tangent of

f (x) = 2 x^{3} - 4 x + 6

y = (6 a_{0}^{2} - 4) x - 4 a_{0}^{3} + 6

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

(a_{0}, 2 a_{0}^{3} - 4 a_{0} + 6)

Find the slope of

f (x) = 2 x^{3} - 4 x + 6 : \frac{df ( x )}{d x} = 6 x^{2} - 4

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 = 6 a_{0}^{2} - 4

Find the line with slope m=

6 a_{0}^{2} - 4

and passing through

(a_{0}, 2 a_{0}^{3} - 4 a_{0} + 6) : y = (6 a_{0}^{2} - 4) x - 4 a_{0}^{3} + 6

y = (6 a_{0}^{2} - 4) x - 4 a_{0}^{3} + 6
