Answer

please see graph (blue curve), asymptote of $h$:$\quad\quad y=1$ domain of $h=(-\infty,\infty)$ range of $h=(1,\infty)$

Work Step by Step

Graph $ f(x)=e^{x}\qquad$ (red, dashed) by plotting the points from the table and connecting with a smooth curve. $h(x)=e^{2x}+1=f(2x)+$1 so the graph of $h(x)$ (blue) is obtained by horizontally compressing the graph of f(x) (red) by factor 2, ... (green dashed) then shifting up by 1 unit (blue). Reading the graph, asymptote of $h$:$\quad\quad y=1$ domain of $h=(-\infty,\infty)$ range of $h=(1,\infty)$
