SOLUTION This solution is FREE courtesy of BrainMass!
Our function is h(u) = [U^2 - 4]^1/4
Please see the figure for the function.
Domain of a function is the set of values for which the expression is true.
Solving for u which makes the expression in the radical sign positive.
U^2 - 4 >= 0
U^2 >= 4
Values given to U must satisfy the above condition.
u=+- 2 will satisfy. u= +- 3 will satisfy. U = 1 will not satisfy. Also anyother value above 2 will satisfy the condition.
thus the domain is [-infinity,-2]U[-2,2]U[2,+infinity]
