Help with interval notation: My prof. Never explained interval notation, so I don't know how to write the answers to these... a) Determine the domain of the function f(x)= {1}{\sqrt{3 x+12}} Domain (in interval notation): Note: Write the answer in interval notation. If the answer includes more than one interval write the intervals separated by the union symbol, U. If needed enter -\infty as - infinity and \infty as infinity . b) Determine the domain of the function f(x) = {-4}/{x^{2}+8x} . I know a) is all real numbers except -4, and b) should be non-zero real numbers.
