Question

this graph models the exponential growth of the strain of bacteria. what does the ordered pair (15, 8) represent? there are 15 bacteria cells after 8 minutes. there are 15 bacteria cells after 8 hours. there are 8 bacteria cells after 15 minutes. there are 8 bacteria cells after 15 hours.

Explanation:

In an ordered pair (x, y) for a graph where x - axis is time and y - axis is the number of bacteria cells, the first value represents the time and the second represents the number of cells. Here, x = 15 (minutes as per x - axis label) and y = 8 (number of bacteria cells).

Answer:

There are 8 bacteria cells after 15 minutes.
