May someone help me find the second derivative of this function? i don't understand how to do so with it being a fraction and having multiple exponents. I also do not know how to find the critical points or concavity of the second derivative so help with that would be greatly appreciated (but not necessary if to much).

ng appropriate mathematical notation and vocabulary. Be sure to show ch claim with appropriate evidence. Given f (xx) = x-1 x2-4 tion Determine the second derivative of the function f " ( y ) ( x - 4 ) f (y ) : need to where lenom . = 6 crit. points
