tangent of y=(-4x)/(x^2+1),(1,-2)

tangent of

y = \frac{- 4 x}{x ^{2} + 1}, (1, - 2)

y = - 2

Solution steps

Find the slope of

y = \frac{- 4 x}{x ^{2} + 1} : \frac{d y}{d x} = - \frac{4 ( - x ^{2} + 1 )}{( x ^{2} + 1 ) ^{2}}

Find the line with slope m=

0

and passing through

(1, - 2) : y = - 2

y = - 2
