$x~~~~~~~~~~~~~~~~~~y=kx^n$ $2~~~~~~~~~~~~~~~~~~~~~~4$ $4~~~~~~~~~~~~~~~~~~~~~32$ $6~~~~~~~~~~~~~~~~~~~~108$ $8~~~~~~~~~~~~~~~~~~~~256$ $10~~~~~~~~~~~~~~~~~~500$
$y=kx^n$ $k=\frac{1}{2}$ and $n=3$ $y=\frac{1}{2}x^3$ $x=2$: $y=\frac{1}{2}·2^3=4$ $x=4$: $y=\frac{1}{2}·4^3=32$ $x=6$: $y=\frac{1}{2}·6^3=108$ $x=8$: $y=\frac{1}{2}·8^3=256$ $x=10$: $y=\frac{1}{2}·10^3=500$
