1.The annual cost C ( in thousands of dollars) and revenue R ( in thousands of dollars) for a company each year from 2010 through 2016 can be approximated by the models

C=254-9t+1.1t to the second power and R=341 +3.2t

where t is the year, with t=10 corresponding to 2010

Please type function P that represents the annual profit of the company.

P(t) = Answer Please Help.


2.Verify that f and g are inverse functions algebraically and graphically.

f(x) = 9x +1, g(x) = Fraction x-1 over 9


f(g(x))=f ( Answer)

=9 ( Answer) +1

=x


g(f(x)) =g (Answer)

= Answer -1

over 9 Fraction


=x


  1. Use the table of values for y=f(x) to type a table for y = f -1exponent (x). (Order your answers from smallest to largest x-value.)

Table x -1 0 1 2 3 4

f(x) 4 6 8 10 12 14


x Answer too Table Row six boxes


f-1 exponent (x) Answer to Table Row six boxes
