The number 2,000 represent the number of bacteria at t = 0 in the function.
<h3>What is an exponent?</h3>
Consider the function:
y = a (1 ± r) ˣ
Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
If there is a plus sign, then there is exponential growth happening by r fraction or 100r %
If there is a minus sign, then there is exponential decay happening by r fraction or 100r %
The population of a certain bacteria can be modeled by the function

Where t represents the number of hours after an experiment has started.
The number 2,000 represent the number of bacteria at t = 0 in the function.

Answer:
x=3 x = -8 x = 11
Step-by-step explanation:
f(x) = (x − 3)(x + 8)(x − 11)
Using the zero product property
0 = (x − 3)(x + 8)(x − 11)
0 = x-3 0 = x+8 0 = x-11
x=3 x = -8 x = 11
The total amount of coins is 8, so the fraction for dimes would be 3/8 because there are three dimes in all. The fraction for quarters would be 2/8 because there are two quarters in all.
