<p>Hi there.</p>
<p>I just finished the second SN Model test for Math IIC
and question 11. asks for this:</p>
<p>Which of the functions graphed below has a range of (5, 5)?</p>
<ul>
<li>So five graphs were given and I chose the one with two horizontal
asymptotes at y=+/- 5.</li>
</ul>
<p>After finishing the test, it said that I was wrong because -5 would be included in the range.
Shouldn't it be written like range [-5, 5)?
Is that my fault or is it a mistake on sparknotes?</p>
<p>Thanks</p>
