Question 1063537
<pre><b>

We build up from {{{y=2^x}}} to {{{y=2^(x+8)}}} to {{{y=2^(x+8)+4}}}  

{{{y=2^x}}} has this red graph

{{{graph(400,400,-15,5,-5,15,2^x)}}}

When we replace x by (x+8) we shift the graph 8 places LEFT.

{{{y=2^(x+8)}}} has this green graph

{{{graph(400,400,-15,5,-5,15,2^x,2^(x+8))}}}

When we add +4 to the right, we shift the graph 4 places UP.

{{{y=2^(x+8)+4}}} has this blue graph

{{{graph(400,400,-15,5,-5,15,2^x,2^(x+8),4+2^(x+8))}}}
