To find the graph of the given function, we
need to analyze the transformations of the exponential - function to :
Horizontal translation:
For the function ,
compared to , the x is replaced by x + 1. So the graph of is shifted to the left by 1 unit to get .
The negative sign in front of
reflects the graph of about the x- axis.
Vertical translation:
The +3 in the function
shifts the graph of up by 3 units.
Consider the key-points and behavior:
The function is an
increasing function, since reflects across the x- axis, it
becomes a decreasing function.
The horizontal asymptote of
