The domain of the function √x(x+2) is ____________. (Write the answer in interval notation.)
Note: If the answer includes more than one interval write the intervals separated by the union symbol, U. If needed enter -∞ as - infinity and ∞ as infinity. Given the function f(x)= √x(x+2)). Calculate the following values (Note: if x is not in the domain type UD for undefined):
f(-1)= _____.
f(1/2)= ____.
f(1)= ____.
