Здравствуйте, Козловский Константин Викторович!
y=x^(2/3) - 20
y'= 2/3 * x^(-1/3)
y(-8) = 4-20=-16
y'(-8) = (2/3) *(-1/2) = - 1/3
y = -16 -1/3 (x+8) - уравнение касательной
уравнение нормали:
y = -16 +3(x+8) = 3x+ 8
y=x^(2/3) - 20
y'= 2/3 * x^(-1/3)
y(-8) = 4-20=-16
y'(-8) = (2/3) *(-1/2) = - 1/3
y = -16 -1/3 (x+8) - уравнение касательной
уравнение нормали:
y = -16 +3(x+8) = 3x+ 8
