Step-by-step explanation:
The domain of a function are the values of that you can plug into the function
.
Values inside of a root must be non-negative, which means that must be greater than or equal to zero. We can set up an equation to find the domain:
With this, we know the domain of the function is .
The range of a function are the values that can have. Since the equation is a cube root, the value will always be non-negative, meaning the range of the function is
.
Answer:
The differential equation is
Step-by-step explanation:
Differential equation for the rate of change in radiation level:
Radiation level is R.
Rate of change indicates that the radiation level R varies in function of time t, which mathematically means that we have:
After the reactor is shut down, the radiation from the nitrogen-17 decreases in such a way that the rate of change in the radiation level is directly proportional to the radiation level.
Rate of change is k. Decreases means that k is negative. Proportional to the radiation level of R means that -k multiplies R. So the differential equation is:
