The diameter of a bacteria colony that doubles every hour is represented by the graph below. what is the diameter of the bacteria after 8 hours? graph of a curve passing through the points zero comma 1, one comma two, two comma four, and three comma eight

Diameter = 256 after 8 hours.

Step-by-step explanation:

At time 0 the diameter is 1, at time 1 hour the diameter is 2, at time 2 hours the diameter is 4 and so on.

The equation of the graph is d = 2^t where d = the diameter and t = time in hours. This is exponential growth.

So after 8 hours the diameter = 2^8

= 256 (answer).
