Question

analyzing an exponential function. the growth of a strain of bacteria can be modeled by the function graphed, where the x - values are the time in seconds and the y - values are the number of bacteria. how many bacteria are there initially? 0 2.7 2.8 4

Explanation:

Step1: Identify initial time

Initial time is when \(x = 0\) as \(x\) - values represent time.

Step2: Find corresponding y - value

From the graph, when \(x = 0\), the point is \((0,2.7)\), so \(y=2.7\). The \(y\) - value represents the number of bacteria.

Answer:

2.7
