poq(x) = 2x² + 4x + 5
q(x) = 2x + 3
q⁻¹(x) = 1/2 (x- 3)

p(x) = (poq)o q⁻¹(x)
p(x) = 2 {1/2(x-3)}² + 4{1/2(x-3)} + 5
p(x) = 2/4 (x-3)² + 2(x-3) + 5
p(x) = 1/2(x²-6x+9) + 2x - 6 + 5
p(x) = 1/2 x² - 3x + 9/2 + 2x - 1
p(x)= 1/2 x² - x + 7/2
p(x) = 1/2 (x² -2x + 7)

vow (x)= (2x-3)/(x+4)
w(x)=  1- x
vow (x) = v{w(x)} = v(1-x)
vow(x) = {(2(1-x) - 3)} / {(1-x + 4)}
vow(x) = (2-2x - 3)/(5 - x)
vow(x) = (-2x -1)/(5 - x) 
atau
vow(x) = (2x -1)/(x + 5)
