Best ResponseYou've already chosen the best response.0In growth and decay questions, the independent variable is usually t, to signify time. Assuming x is signifying time here, the initial time would be when x = 0... so that should be a big enough hint as to what the initial amount is. The decay factor is normally the percentage the initial amount will decay over a time period. It would be 1  BASE, where BASE is the base of the exponent (x in this case).
