[tex]h(x)=0.5(2)^x^{}[/tex]
We can compute the growth percentage, computing first, two consecutive values, as follows:
[tex]\begin{gathered} h(1)=0.5(2)^1=0.5(2)=1 \\ h(2)=0.5(2)^2=0.5(4)=2 \end{gathered}[/tex]
Then, the growth percentage is:
[tex]\frac{h(2)-h(1)}{h(1)}\cdot100=\frac{2-1}{1}\cdot100=100\text{ \%}[/tex]
