2000 is the y-intercept, it is the amount of money in the account initially.
<h3>
Exponential function</h3>
An exponential function is in the form:
y = abˣ
where a is the initial value of y, b is the multiplier, y, x are variables.
Let y represent the amount in the bank after x years.
Given the function y=2000(0.64)ˣ
Hence:
a = 2000, b = 0.64
0.64 = 1 + x
x = -0.36 (36% decrease)
2000 is the y-intercept, it is the amount of money in the account initially.
