Helena Trevino · Answer 1

We are given the equation y = 2 (x - 3) ^2 - 4 and is asked for the domain and range of the following function. In this case, there is no radical sign so the domain includes all real numbers. The range has a minimum value of - 4 since the squaring makes the value on the first term positive. Hence the answer is A.
