A scientist counts 35 bacteria present in a culture and finds that the number of bacteria triples each hour. The function y = 35 • 3x models the number of bacteria after x hours.

Graph the function. (You do not need to submit the graph).

Use the graph to estimate when there will be about 550 bacteria in the culture.

anonymous · Answer

The concept here would be that y= 35 * 3x
Then graph y=550
find the intersection point symbolizing point at which bacteria in the culture will be equal to 550. The x value at that point will be the time (in hours)
