Best ResponseYou've already chosen the best response.0what did u get for the result for L(x) ? So that I don't have to work it out again

Best ResponseYou've already chosen the best response.0im at sqrt (16x)+1/2(16x)^1/2

Best ResponseYou've already chosen the best response.0So in this case to approximate: sqrt(15.9) is approximately f(16) + f'(16) * (1615.9)
