A. 0.64 is the percent of money in the account after years
B. 2000 is the -intercept, it is the amount of money in the account initially
C.0.64 is the percent of money in the account initially
D.2000 is the -intercept, it is the amount of money in the account after years

Answer 1

2000 is the y-intercept, it is the amount of money in the account initially.

Exponential function

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.
