Question

The estimated number of users of one program from 1995-2005 defines a function that has a y-value for every x-value in the interval However, the table shows data for just six x-values. Let y = f(x) represent the number of users and x represent the years. What is the independent variable? The function f The years There are no independent variables The number of users What is the dependent variable? The number of users The function f The years There are no dependent variables Find f(1999). f(1999)= million The estimated number of users of one program from 1995-2005 defines a function that has a y-value for every x-value in the interval However, the table shows data for just six x-values.
