Best ResponseYou've already chosen the best response.0because the value of that fraction is equal to zero only when the numerator, or x plus two is equal to zero. x+2 = 0, x= 2 click on Become a fan if I helped. Thanks.

Best ResponseYou've already chosen the best response.0\[f(x)=(x+2/3)^{2}\] is the equation to which we are referring, correct? If so, f(2)=16/9
