Answer:
The solution is the interval (-∞,5]
Step-by-step explanation:
we have
The solution is the interval -----> (-∞,5]
All real numbers less than or equal to 5
In a number line the solution is the shaded area at left of x=5 (close circle)
see the attached figure
The population size after 6 years and after 8 years are 147 and 169 population respectively
<h3>Exponential functions</h3>The standard exponential function is expressed as y = ab^x
where
a is the base
x is the exponent
Given the function that represents the population size P (t) of the species as shown;
For the population size after 6 years
For the population after 8 years
Hence the population size after 6 years and after 8 years are 147 and 169 population respectively
