Answer:

A. It is the sum of the initial amount and the additional amount after d days.

Step-by-step explanation:

We have been given an expression 100+0.25(d-1), which gives the total amount of money in Jennifer's savings account after d days.

Since Jennifer adds $0.25 each day after first day, so amount in Jennifer's account after d days would be 100 plus 0.25 times d minus 1 day.

Since Jennifer "adds" an amount each day, therefore, the expression is the sum of initial amount and the additional amount after d days.

F(x) and g(x) were inverse functions, then if f(a) = b, then g(b) = a

f(x) = (5x+1) / x g(x) = x / (5x+1)

f(1) = 6, but g(6) = 6/31 ≠ 1

So, f(x) and g(x) are NOT inverse functions.
