y=log_2(\frac{x}{8}-\frac{1}{4})=log_2(\frac{x-2}{8})=log_2(x-2)-log_28

$  =log_2(x-2)-3=log_2(x-h)+k$

$ ∴h=2,k=-3 $

f(x)=log_2x

$ g(x)=log_2\left( \frac{x}{8}-\frac{1}{4}  \right) $

h(x)=log_2(x-2)

f(x) = ld(x)
g(x) = ld(x - 2) - 3
n = 1 (slider from 1 to 5, step 1)
poly1, a, b, c, d = Polygon(Corner[1], Corner[2], Corner[3], Corner[4])
u = Vector((x(Corner[1]), 0), (x(Corner[3]), 0))
v = Vector((0, y(Corner[1])), (0, y(Corner[3])))
h(x) = f(x - 2)
