The house-numbers on a certain street go from 1 to 88. The function B(n) models the type of the building whose number is n according to the following key: (Type of Building : Function Output)
Residential building : 0
Commercial building : 1
Government building : 2
Other : 3
Which number type is more appropriate for the domain of B?
A) Integers
B) Real numbers
What's the appropriate domain?
A) 1≤n≤3
B) 0≤n≤3
C) 1≤n≤88
D) 0≤n≤88

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
