Answer:
The reasonable domain to plot the growth function is the interval [0,9]

Step-by-step explanation:
In this problem we have a exponential function of the form

where
f(d) is the radius of the algae in mm
d is the number of days
a is the initial value or y-intercept
b is the base
r is the rate of growth
b=1+r
we have

we have

For f(d)=12.81 mm
substitute in the function and solve for d


Apply log both sides




therefore
The reasonable domain to plot the growth function is the interval [0,9]

When you cut a cone parallel to the base , you will see a circle
