The Chicago cubs franchise has been in existence since $1876$.

The total season attendance for its home games can be modeled by $f\left ( x \right )=21870x-40962679$.

Where $x$ represents the year.

The function $f\left ( x \right )=21870x-40962679$ is a linear function.

All possible values of $x$ is domain of a function.

Linear function domain is all real numbers.

Because the number of years must be a whole number, the relevant domain of the function is the set of whole numbers greater than or equal to $1876$.

Domain set is $\left \{ x|x\geq 1876,\ x\ \epsilon \ W \right \}$.

Domain set is $\left \{ x|x\geq 1876,\ x\ \epsilon \ W \right \}$.
