The required explicit formula to represent the amount of beach remaining each year will be y = a(0.011)^x

Exponential functions

Exponential functions are inverse of trigonometry functions. The standard form of exponential function is expressed as:

y = ab^x

b is the rate

Given;

Rate = 1.1% = 0.011

The required explicit formula to represent the amount of beach remaining each year will be y = a(0.011)^x
