Answer:
Domain = [0,∞)
Step-by-step explanation:
The given function is
[tex]y=0.99x[/tex]
where, y is the price of x in game power boost.
Domain is the set of input values or x-values.
It means the reasonable domain of the given function is the possible number of games. So, domain of the given function can't be negative.
Set builder form of domain is
[tex]Domain=\{x: x\geq 0,x\in R\}[/tex]
Interval notation of domain is
[tex]Domain=[0,\infty)[/tex]
Therefore, the reasonable domain for the given function is [0,∞).
