tangent of 3x-4x^2

tangent of

3 x - 4 x^{2}

y = (3 - 8 a_{0}) x + 4 a_{0}^{2}

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

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

Find the slope of

y = 3 x - 4 x^{2} : \frac{d y}{d x} = 3 - 8 x

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 = 3 - 8 a_{0}

Find the line with slope m=

3 - 8 a_{0}

and passing through

(a_{0}, 3 a_{0} - 4 a_{0}^{2}) : y = (3 - 8 a_{0}) x + 4 a_{0}^{2}

y = (3 - 8 a_{0}) x + 4 a_{0}^{2}
