y = a(x-0)(x-2) melalui (1,3) --> 3 = a(1-0)(1-2)
3 = a(1)(-1)
3 = -a
a = - 3
pers kurva y = -3(x)(x-2) --> y = -3(x² - 2x)
y= - 3x² + 6x
Luas daerah arsiran = L =
L = ₁²∫-3x² + 6x dx - ₂³∫ - 3x² + 6x dx
L = [-x³ + 3x²]²₁ - [-x³ +3x²]³₂
L = [ -(2³-1³) + 3(2²-1²) - [ -(3³-2³) + 3(3²-2²)]
L = (- 7 + 9) - (-19 + 15)
L= 2 -(-4)
L = 2+4
L = 6
