You need to define domain and range but I can tell you this much.
For real values x cannot equal 4 because division by 0 is undefined
And x cannot be less than 4 or the square root of (x-4) is imaginary; not a real number.
Therefore x > 4
Also, as x approaches infinity h(x) goes to -0
And, as x approaches 4, from the positive side of 4, h(x) goes to negative infinity.
Therefore -infinity <= h(x) <= -0 or zero(minus)
