<p>No, I clearly remember there was an option choice with always decreasing, that’s the one I chose.</p>
<p>@rubi32</p>
<p>When you say “less than or equal to 0,” the domain (set of values for x) includes both 0 and all numbers less than 0 (all negative numbers). </p>
<p>If |x| = -x, then x must be zero or a negative number, for:
|0| = -0 → 0 = 0 (which is true)
AND<br>
|-7| = -(-7) → 7 = 7 (which is true)</p>
<p>The question is not unclear and will not be stricken from the reports. Yes, 0 is a part of the domain, but it is not all of the domain. Hence, the correct answer as well as the only logical answer is x < 0, or x is less than or equal to zero.</p>
<p>Hope I cleared up any confusion. :)</p>
<p>I put always decreasing.</p>
<p>I think that one was increasing until 1. Then decreasing afterwards. Since a^-x is the same as a/x, a number under one will cause an increase. ex: a/.5 will result in 2a.</p>
<p>@redkeyboard a^(-x) = 1/a^x</p>
<p>Ahh I see, another one I got wrong then. I should really double check things with my calculator before assuming anything lol.</p>
<p>what was the question where the answer was 1 and 2</p>
<p>@set1012
It was the question about when the rocket was 32 feet in the air. Both 1 and 2 worked in the equation, but the correct answer was at 1 second because it was still going up in the air then.</p>
<p>has anyone compiled a list of the difficult questions at least? If not, anyone willing to do so?</p>
<p>Oh yea… I remember ALL the questions ya’ll are talking about I gussed B…lol…jk… jk</p>
