(1 point) The following table gives the number \( f ( x ) \) of free exercise classes that are offered each year at MSU, where \( x \) is the number of years since \( 2000 .\) 

(a) Viewing the table as a numerical representation of a linear function, give an equation for this function. 

\(f ( x ) = \square \quad \)

(b) Determine the \( x \) -intercept(s): \( \square\)

(c) Interpret the meaning of your answer from part (b): 

In the year \( \square\),\(\square\) free fitness classes were offered at MSU.
