Question

solving exponential and logarithmic equations pre - test complete 1 based on the graph, what is the approximate number of bacteria after 16 hours?

Explanation:

Step1: Locate 16 on x - axis

Find the value of 16 on the time (x - axis) scale.

Step2: Read corresponding y - value

Move vertically from x = 16 until intersecting the curve, then move horizontally to read the y - value (number of bacteria). From the graph, when x = 16, the y - value is approximately 40.

Answer:

40
