Answer:
Option B) There is a 3 percent increase in the savings account each year.
Step-by-step explanation:
we have

This is a exponential function of the form

where
M(x) represent the amount of money in a saving account
x represent the number of years
a is the original deposit (y-intercept)
b is the base
r is the rate or percent increase

The percent increase per year is the base of the exponential function decreased by 1.
so

In this problem we have
---> original deposit

Therefore
The percent increase per year is 3%
The easiest way to solve this problem is by using the Pythagorean theorem :D
Pythagorean theorem: [-b +- sqrt(b^2 - 4ac)]/2a
5 = a
-1 = b
6 = c
therefore, by plugging these values in!
[-(-1) +- sqrt((-1)^2 - 4(5)(6))]/2(5)
[1 +- sqrt(1 - 120)]/10
Oh so we're using imaginary numbers, so in this case you'll need to know that i = sqrt(-1), so keep this in mind (I can see why this was so difficult)
[1 +- sqrt(119)*i]10
answers:
( 1 + i*sqrt(119) ) / 10
( 1 - i*sqrt(119) ) / 10
