Let hx squareroot x2 and let kx squareroot 2 x For what v
     Let h(x) = squareroot x-2 and let k(x) = squareroot 2 - x. For what value(s), if any, are the functions undefined? If the functions are undefined for a range of values, enter these values in interval notation.  Enter the interval where the function h(x) is undefined:  Enter the internal where the function k(x) is undefined:  You have attempted this problem 3 times.  Your overall recorded score is 0 %.  You have 3 attempts remaining. 
  
  Solution
h(x) = sqrt( x-2) ; k(x) = sqrt(2 -x)
h(x) is undfined for (x-2) <0
So, x<2
Interval notation : ( -infinity , 2) ---------> (open interval )
k(x) is indefined for (2-x)<0
x>2
So, interval notation : ( 2, infinity) ---------> (open interval )
