tangent of f(x)=(x^2-4)^2

tangent of

f (x) = (x^{2} - 4)^{2}

y = 4 a_{0} (a_{0}^{2} - 4) x - 3 a_{0}^{4} + 8 a_{0}^{2} + 16

Solution steps

Compute the tangent line to the general point

x = a_{0}

Find the tangent point:

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

Find the slope of

f (x) = (x^{2} - 4)^{2} : \frac{df ( x )}{d x} = 4 x (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 = 4 a_{0} (a_{0}^{2} - 4)

Find the line with slope m=

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

and passing through

(a_{0}, (a_{0}^{2} - 4)^{2}) : y = 4 a_{0} (a_{0}^{2} - 4) x - 3 a_{0}^{4} + 8 a_{0}^{2} + 16

y = 4 a_{0} (a_{0}^{2} - 4) x - 3 a_{0}^{4} + 8 a_{0}^{2} + 16
