Question 1153126: What is domain and range, use interval notation
x + 2 / x^2 + 2x -8
so... x^2 + 2x - 8 cannot be 0
also... (x + (-2)) (x + 4) cannot be 0
and... x cannot be 2, x cannot be -4
is Domain (-infinity,-4) u (-4,2) u (2,infinity)
is Range all real numbers ?

domain:{ x element R : x%3C%3E-4 and x%3C%3E2 }
(assuming a function from reals to reals)
range: R (all real numbers)
