use function notation to represent this statement.
in 2012, about 1.04 billion people owned a smartphone.
p(12) = 1040
p(1040) = 2012
p(2012) = 1040
p(1040) = 12
question 7

explain the meaning of each statement in this situation.
w(5) > w(2)

Explanation:

Step1: Understand function notation

Function notation \(P(x)\) means the function \(P\) evaluated at \(x\). Here, \(x\) is the input (usually the year) and \(P(x)\) is the output (number of smartphone - owners in millions, for example).

Step2: Analyze the values

We know that the year is \(2012\) and the number of people is \(1.04\) billion. Since \(1\) billion \( = 1000\) million, \(1.04\) billion \(=1040\) million. In function notation, if the input \(x\) represents the year and \(P(x)\) represents the number of smartphone - owners (in millions), then when \(x = 2012\), \(P(2012)=1040\).

Answer:

C. \(P(2012)=1040\)
