<p>From Sparks' practice,
The range of a function is the set of all values of f(x). In the answer choice graphs, y = f(x), so to find the range of a function given the graph of that function, only observe which values of y are contained in the graph. If the range of a function is<a href="%C2%965,%205">b</a>**, this means that 5 is included in the range, but 5 is not. (The range is said to be inclusive of 5 but exclusive of 5.) The function whose graph shows this trait is the first one.

<p>If I remember correctly [-5,5) is used to denote a "closed-open" interval.</p>
<p>Is Sparks' explanation true or is it just a typo?</p>
