Best ResponseYou've already chosen the best response.0(2a+14) / (3a+21) > [2 (a+7)] / [3 (a+7)] > 2/3 That is the solution. *

Best ResponseYou've already chosen the best response.0(2a+14) / (3a+21) = [2 (a+7)] / [3 (a+7)] = 2/3, except a=7

Best ResponseYou've already chosen the best response.0no this is not a situation of an asymptote at a=7 the limit as a>7 is 2/3 Notice at a=7 the function is 0/0 which is indeterminate not undefined L'Hopitals rule says differentiate leaving 2/3 as limit therefore function equals 2/3 for all values of a because (a+7) cancels out you generally dont need to worry about the (a+7) in the denominator
