Function g can be thought of as a translated (shifted) version of f(x) = x. What is the equation of g(x)

The population of a small rural town in the year 2006 was 2,459. the population can be modeled by the function below, where f(x residents and t is the number of years elapsed since 2006. f(t) = 2,459(0.92)

X+y=-4 x-y=2 use elimination with adding and subtraction
