The domain of the profit function P(R) is
D = {R|R∈W|0≤R≤2000}
Step-by-step explanation:
Find the highest and lowest R values for R(t).
R(t) = 10t
Since the maximum number of people is 200, t ≤ 200.
You can't have a negative number of people, so t ≥ 0.
Sub t for 0
R(t) = 10t
R(0) = 10(0)
R(0) = 0
(0,0)
Sub t for 200
R(t) = 10t
R(200) = 10(200)
R(200) = 2000
In R(t), 0 ≤ R and R ≤ 2000.
In R(t), Range = {R|R∈W|0≤R≤2000}
Use 0 ≤ R ≤ 2000 to find the domain of P(R).
The domain in P(R) is the possible values of R because it's in the brackets.
We already know the possible values of R.
Domain = {R|R∈W|0≤R≤2000}
It sets the variable for domain, states the type of numbers R includes, and the specific numbers.
Whole numbers are numbers that are not partials starting from 0.
If you wanted to find the range of P(R), you would substitute R for 0 and 2000 in the equation to calculate the highest and lowest numbers of P.
