The function f(x) = 14.5 -0.25x2 is used to model the curve of a train tunnel, where x is the distance from the
center of the tunnel, and the x-axis represents the
ground. The mathematical range for the function is the
set of real numbers less than or equal to 14.5.
Which statement describes how the reasonable range differs from the mathematical range?

109 is the nearest whole number/final answer! : )

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,
