When you subtract 3 from the exponent in an exponential function of the form \( f(x) = a \cdot b^{(x - c)} \), where \( c \) is a constant, you are effectively shifting the graph to the right by 3 units. This is because the transformation involves \( f(x - 3) \), which means the entire function is evaluated at \( x - 3 \).
Therefore, the correct response is:
D It would move to the right 3.
