Well, we can see that 115x refers to something that increases by 115 per purchase, while the 100 refers to a one time cost. Out of the possible answers the only one time charge is the installation charge, which refers to the 100$, and the 115x refers to the computers. In 115x, the 115 refers to how much a computer costs, and the x refers to the number of computers.
I believe they are called opposites.
Part A
The exponential model that describes the situation
The formula is
Y (x)=400 (1+0.02/4)^4x
Y (x)=400 (1+0.005)^4x
Y (x)=400 (1.005)^4x
Where x is the number of years
Part B
The value of the account after 5 years
Y (5)=400×(1.005)^(4×5)
Y (5)=441.96
i believe the answer is concave
