Best ResponseYou've already chosen the best response.0f(x)=13.333(x  3)^2+120 is the equation f(5)=13.333(x  5)^2+120 f(5)=13.333x^2333.33 @Shalante is this right so far?

Best ResponseYou've already chosen the best response.0Do not change anything besides the x Plug in x=5 and x=3 Subtract f(5)f(3) Divide it by 2 since that is the interval difference.

Best ResponseYou've already chosen the best response.0f(x)=13.333(5  3)^2+120 is the equation f(5)=13.333(2)^2+120 f(5)=13.333(4)+120 ?

Best ResponseYou've already chosen the best response.0ok and then f(x)=13.333(x  3)^2+120 f(3)=13.333(3  3)^2+120 f(3)=13.333(0)+120 f(3)=120 ?

Best ResponseYou've already chosen the best response.0the rate of the profit they are getting. rate is change of y. y is f(x) f(x) is the profit.
