What is the domain and range of #y+2 = (x-3)^2#?
The function you provided is almost in vertex form of a quadratic function, which helps greatly when answering your question. Vertex form in a quadratic is when the function is written in the following form:
To write your function in vertex form, I'll simply solve for
The two parameters you want in this are
Now we need the range. As stated before, it comes from the values of
