how do i find the critical numbers for cube root of X+2 . I took the derivative of this and got (1)/[3(x+2)^(2/3)]. is the next step setting this expression equal to 0?

Best ResponseYou've already chosen the best response.0so I have to substitute a value for x that will make this expression > (1)/[3(x+2)^(2/3)]. equal 0?

Best ResponseYou've already chosen the best response.0if I substitute 2 for x, the entire denominator equals 0. so would 2 b my critical number?

Best ResponseYou've already chosen the best response.0yes you cant find a number that can make your derivative equal to 0 so 2 is the only critical number
