y = 3/4 x²- 3x
y = 3/4 (x² - 4x)
y = 3/4 (x² -4x + 4)-  4(3/4)
y = 3/4 (x -2)² - 3
y = a(x-p)² + q
p = 2 , q = -3
titk puncak (p,q) = (2, -3)

y = 1/2 x²+2x + 3
y = 1/2 (x² + 4x) + 3/2
y = 1/2 (x² + 4x + 4 ) - 4(1/2) + 3/2
y = 1/2 (x+2)² - 1/2
y = a(x-p)² + q
p = -2, q = -1/2
titik puncak (p,q) = (-2, - 1/2)
