Solution for y=-5x^7/x^8-6 equation: 


D( x )

x^8 = 0

x^8 = 0

x^8 = 0

1*x^8 = 0 // : 1

x^8 = 0

x = 0

x in (-oo:0) U (0:+oo)

y = (-5*x^7)/(x^8)-6 // - (-5*x^7)/(x^8)-6

y-((-5*x^7)/(x^8))+6 = 0

5*x^-1+y+6 = 0

5*x^-1 = -(y+6) // : 5

x^-1 = (-(y+6))/5

-1 < 0

1/(x^1) = (-(y+6))/5 // * x^1

1 = x^1*((-(y+6))/5) // : (-(y+6))/5

-5*(y+6)^-1 = x^1

x = -5*(y+6)^-1

x = -5*(y+6)^-1
