(a) The factor, b, equals
(b) The y-intercept, a, equals
(c) The rate of the function, written as a DECIMAL, equals
(enter your answer with a negative if the rate is negative!)
(d) The rate of the function, written as a PERCENTAGE,
equals
%
(enter your answer with a negative if the rate is negative!)
(e) Write the equation of the function:
$f(x) =$
