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 )
