Behavior of the Exponential Term:
As x approaches negative infinity, the term 3^(x−3) will tend to zero.
This is because any positive base b raised to a very large negative exponent approaches 0:

Impact of k:
If b > 1 or 0 < b < 1, then 3^(x−3) → 0 as x → −∞.
The constant k shifts the entire graph vert...
