The answer for this question is 4.
Answer:
Step-by-step explanation:
If $10,000 is invested at an interest rate of 2% per year, compounded semiannually, find the value of the investment after the given number of years. (Round your answers to the nearest cent.)
a)6 years
b)12 years
c)18 years
***
compound interest formula: A=P(1+r/n)^nt, P=initial investment, r=interest rate, n=number of compounding periods per year, A=amt after t-years.
For given problem:
P=10000
r=.02
n=2
t=6, 12, 18
..
A(6)=10000(1+.02/2)^2*6
A(6)=10000(1.01)^12=11,268.25
A(12)=10000(1.01)^24=12,697.35
A(18)=10000(1.01)^36=14,307.69
Answer:
The one in the middle would be the quadratic function. I know this because of how when it gets to 10, it starts to repeat the other two numbers behind it.
Step-by-step explanation:
Answer: C
The graph is continuous because there can be fractional values for time
Answer: Choice D) 
The steps to finding the inverse will have us swap x and y. Afterward, we solve for y
------------------------------
Extra info:
The inverse relation is not a function because of the plus minus. For instance, plugging x = 4 into leads to y = -3 and y = 3 simultaneously. You would have to apply a domain restriction on 
to make it a one-to-one function, to make the inverse a function. One possible domain restriction is 
which would lead to the inverse function
