A$3000 deposit for 66 months compounded at an interest rate of 1.6% .

The correct question is

t=66 months >66/12=5.5 years

F = P*(1 +(r/m))^n

r=1.6% >0.016
m=12 (number of compounding periods per year)

n=m*t >12*5.5=66
we have
P=3000
t=5.5 years
F = 3000*(1 +(0.016/12))^66 >3275.77 dollars

 the answer is 3275.77 dollars 

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)
