tangent of y=-(8x)/(x^2+1),(1,-4)

tangent of

y = - \frac{8 x}{x ^{2} + 1}, (1, - 4)

y = - 4

Solution steps

Find the slope of

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

Find the line with slope m=

0

and passing through

(1, - 4) : y = - 4

y = - 4
