Fred placed 3 strands of bacteria in a petri dish. The bacteria strands double every hour. Write a formula to represent how many bacteria strands are present at the nth hour. Then, use the formula to determine how many strands of bacteria are present at 4 hours.

Question 10 options:

f(n) = 2(3)n; 82 strands of bacteria


f(n) = 3(2)n; 48 strands of bacteria


f(n) = 2(3)n; 162 strands of bacteria


f(n) = 3(2)n; 59 strands of bacteria
