Misalkany = ²logx , maka bentuk pertidaksamaan menjadi
y² - 2y - 8 < 0
(y + 2)(y - 4) < 0
-2 < y < 4
(i)
y > -2
²logx > -2
x > 2⁻²
x > 1/4
(ii)
y < 4
²logx < 4
x < 2⁴
x < 16
jadi HP = {x| 1/4 < x < 16}
y² - 2y - 8 < 0
(y + 2)(y - 4) < 0
-2 < y < 4
(i)
y > -2
²logx > -2
x > 2⁻²
x > 1/4
(ii)
y < 4
²logx < 4
x < 2⁴
x < 16
HP = {x| 1/4 < x < 16}
