Question 210173
 when a constant is added to an exponent how is a graph affected? 
when a constant is added to the base how is a graph affected?
----------------------------------
If you start with y = 2^x you get:
{{{graph(400,300,-10,10,-10,10,2^x)}}}
-------------------------------------------
If you add a constant you might get y = 2^(x+2)
That will shift the graph 2 units to the left.
{{{graph(400,300,-10,10,-10,10,2^(x+2))}}}
======================================================
But if you add a negative number the graph will shift to the right:
{{{graph(400,300,-10,10,-10,10,2^(x-2))}}}
========================================
