<p>According to sparknote: "If the range of a function is (5, 5), 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.) "</p>
<p>I don't remember learning anything about this. I thought range was just the possible values of y?</p>
<p>What you mean to say is [-5,5). The bracket "[" means inclusive and the parenthesis ")" means exclusive (and same applies for "]" and "(").</p>
<p>That's nice to know, thanks!
I didn't type this, it was a cut and paste. Sparknote made a typo I guess. So if they used (-5,5) instead of [-5,5), then I was actually right! lol
Thanks again!</p>
