Answer:The number of bacteria increases by 20% each hour.
Step-by-step explanation: this is if your looking at the multiple choice question
From the graph, the initial sample of the bacteria will be 50.
Let a be the initial value and x be the power of the exponent function and b be the increasing factor.
The exponent is given as
y = a(b)ˣ
A sample of bacteria was placed in a petri dish.
The number of bacteria changes exponentially over time.
The graph describes the number of bacteria over time (in hours).
Then the sample's initial size will be
We know that the initial sample is obtained when x = 0. Then we have
y = a
From the graph, the initial sample of the bacteria will be 50.
