Answer 1

The function that can be used to find the number of bacteria present at the end of \( h \) hours, given that the bacteria double every hour and you start with 20 bacteria, is:

B: \( n = 20(2^h) \)

This is because the number of bacteria at any time \( h \) can be modeled by the initial quantity (20) multiplied by \( 2 \) raised to the power of \( h \) (representing the doubling every hour).
