A company that manufactures skateboards uses the function below to estimate f(x), its monthly revenue in dollars, based on x, the number of skateboards manufactured
each month.
f(x) = -0.01x + 45x - 2,400
Which is the best choice for the domain of f(x) in this situation?
all integers > 0
all real numbers
all integers
all real numbers > 0

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
