The right answer is: g(x) is translated 2 units up from f(x)
Step-by-step explanation:
Given functions are:
In order to shift the functions upward or downward, an integer is added or subtracted from the original function's output.
We can see by comparing both functions that 2 can be added to f(x) to make function g.
As 2 is added to the function, not the input, it is a vertical shifting.
As the integer is positive, the shift is upward.
So,
The right answer is: g(x) is translated 2 units up from f(x)

Answer:
The function that represents the mass of the sample after t days is 
.
The percentage rate of change per hour is of -2.46%.
Step-by-step explanation:
Exponential amount of decay:
The exponential amount of decay for an amount of a substance after t days is given by:
In which A(0) is the initial amount, and r is the decay rate, as a decimal.
Element X is a radioactive isotope such that its mass decreases by 59% every day. The experiments starts out with 390 grams of Element X.
This means, respectively, that 
So
The function that represents the mass of the sample after t days is .
Hourly rate of change:
Decreases by 59% every day, which means that for 24 hours, the rate of change is of -59%. So
-59%/24 = -2.46%
The percentage rate of change per hour is of -2.46%.
