A mathematical model that represents these data is
f(x) =-1.96x + 25.6
(0.533x2 - 1.53x + 5.9. What is the domain of each part of the piecewise-defined function? (Enter your answers using interval notation.)
Domain: -1.96x + 25.6
X=
Domain: 0.533x&lt; - 1.53x + 5.9
X=
(b) Find f(5) and f(11). (Round your answers to one decimal place.)
f(5) =
f(11) =
Interpret your results in the context of the problem.
O These values represent the revenue in thousands of dollars for the months of March and October, respectively.
O These values represent the revenue in hundreds of dollars for the months of March and October, respectively.
O

O
These values represent the revenue in hundreds of dollars for the months of May and November, respectively.
O
These values represent the revenue in thousands of dollars for the months of May and November, respectively.
(c) How do the values obtained from the model in part (a) compare with the actual data values?
There is no correlation between the model values and the actual values.
O
There are more actual values than model values.
O
The model values match the actual values exactly.
O
The model values are quite close to the actual values.
O There are more model values than actual values.
