tangent of f(x)=2x^4-11x^2,\at x=2

tangent of

f (x) = 2 x^{4} - 11 x^{2}, at x = 2

y = 20 x - 52

Solution steps

Find the tangent point:

(2, - 12)

Find the slope of

f (x) = 2 x^{4} - 11 x^{2} : \frac{df ( x )}{d x} = 8 x^{3} - 22 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 = 20

Find the line with slope m=

20

and passing through

(2, - 12) : y = 20 x - 52

y = 20 x - 52
