tangent of f(x)=(-8x)/(x^2+1),(0,0)

tangent of

f (x) = \frac{- 8 x}{x ^{2} + 1}, (0, 0)

y = - 8 x

Solution steps

Find the slope of

f (x) = \frac{- 8 x}{x ^{2} + 1} : \frac{df ( x )}{d x} = - \frac{8 ( - x ^{2} + 1 )}{( x ^{2} + 1 ) ^{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 = - 8

Find the line with slope m=

- 8

and passing through

(0, 0) : y = - 8 x

y = - 8 x
