Functions, again

Problem:



Suppose the function k gives the cost of a Chevy Equinox in terms of the number of years since 2007 and the function s gives the cost of a Honda CRV in terms of the number of years since 2007

Part a) What does the expression 2s(3) represents

Part b) User function notation to represents how much more a Honda CRV cost than a Chevy Equinox in 2017

Part c) Use function notation to represents how much more a Chevy Equinox costs in 2017 than 2007

Solution:

Part a)  The cost of 2 Honda CRV in 2010

Part b)  s(10) - k(10)

Part c)  k(10) - k(0)
