1.) у=1/2х^4 - 1/х - 4√х
y`=2x³+1/x²-2/√x
2.) у= ln9х × сos(8x+4)
y`=9/9x *cos(8x+4)-8sin(8x+4)*ln9x=1/x*
cos(8x+4)-8sin(8x+4)*ln9x
3)
у=х^4 - 2х^2 -3=(x²-1)²-4
Строим y=x^4
x      -2      -1        0      1        2
y       16       1      0      1        16
Сдвигаем ось оу на 1 влево и ось ох на 4 вверх
(если двигаем график ,то на 1 вправо и на 4 вверх
