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%28400%2C300%2C-10%2C10%2C-10%2C10%2C2%5Ex%29
-------------------------------------------
If you add a constant you might get y = 2^(x+2)
That will shift the graph 2 units to the left.
graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C2%5E%28x%2B2%29%29
======================================================
But if you add a negative number the graph will shift to the right:
graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C2%5E%28x-2%29%29
========================================
