A company has tracked the relationship between the number of units
of an item that sold, x, (measured in thousands) and the total revenue
earned from the item in dollars, A. The company decided to perform an
exponential regression and found the function A( x) = 223.7 e 0.04x
with r 2 = 0.76. The company uses this model to predict that when it
sells 180,000 items, its revenue will be approximately $300,000.Is this a
valid conclusion and why?
No, an accurate prediction cannot be made when x = 180 because it is
too far from the known data values.
A company's total monthly cost is given by the linear function C( x) =
11,000 + 550 x , where C is the total monthly cost and x is the number
,of units produced each month. The graph of the function is given
below: What does the y-intercept represent in this situation?
If 0 items are produced, the monthly cost is $11,000.00.
A local business is looking to become a franchise. The company wants
to predict the number of franchises, F, given a certain number of years,
Y. This prediction is modeled by the function F( Y). What can be
concluded by F(5) = 10?
In 5 years, there will be 10 open stores.
A bank begins a marketing campaign to increase its number of
customers. Each month, all new customers are put into a drawing. One
customer then receives a $50 credit in a checking account.The amount
of money given away in the drawing, G, is a function of the number of
months, M, the drawing has been going on for. What is the correct
,function notation to represent the amount of money given away after
the drawing has been going on for 5 months?
G(5) = 250
The volume of calls, V( h), at a particular customer service center can be
written as a function of the number of hours after opening each day, h.
What would the ordered pair (6,8) represent for this function?
There were 8 calls 6 hours after opening.
A company has developed two functions, L( t) and M( t), that determine
the least amount and most amount, respectively, of revenue it will
make in any given month in dollars (with t = 1 corresponding to
January). What can the company reasonably conclude if L(2) = 3,000
and M(2) = 5,000?
, In February, it will make between $3,000 and $5,000.
A server at a restaurant has realized that tips, T, in dollars are related to
the number of hours, h, that have been worked on any given day. Tips
can be modeled by the function T( h) = X. How can this function be
interpreted?
If the server works h hours, the tips will be $ X.
A company pays its employees a base salary each month plus a
commission, C, based on the number of sales, s, made by an employee
during the month. An employee made 8 sales in the last month and
received a commission of $1,600. How would this be represented in
function notation?
