Jason writes the following function to represent the amount of money in his account after 7 years given quarterly compounding of the $2430 initial deposit.
f(t)=2430(1.04)^28

a. rewrite the equation in the form f(t)=a(1+r/n)^nt

b. what is the annual interest rate?

The APR is 16%.

Step-by-step explanation:

Jason writes the following function to represent the amount of money in his account after 7 years given quarterly compounding of the $2430 initial deposit as  

......... (1)

a. If we want to rewrite the equation in the form  

.......... (2)

Then comparing equation (1) and (2) we get, A = 2430 and t = 7

Hence, 7n = 28

⇒ n = 4

Now,

⇒ r = 0.16 i.e. 16%  

Therefore, the expression is  

(Answer)

b. The APR is 16%. (Answer)

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
