<p>wait can someone type up that union set question</p>
<p>These questions have all been answered in the past… </p>
<p>y=x is 4
parabola tangent = 4
union is all except 0</p>
<p>iknow. but i dont remember what my answer was so i would like to see the question for the union one.</p>
<p>can someone who knows the answer to the f(X) question explain how they confirmed it on their calculator </p>
<p>the question was that (3,5) was a point on f(x) so which of the following points is part of f (x-1)?</p>
<p>i thought for sure that the answer was not (3,5)
was there a not enough information choice for this one?</p>
<p>you don’t need a calculator for this question…</p>
<p>Q: f(2) = 5. what point satisfies f(x-1)=y?</p>
<p>Let’s just pretend that x = 3. then what is x-1?
x-1 = 3-1 = 2. </p>
<p>Then what is f(x-1)?
f(x-1)=f(3-1)= f(2). </p>
<p>What is f(2)?
f(2) = 5 (given).</p>
<p>So it doesn’t matter what the function f is, all that we know is that 3,5 satisfies f(x-1) = y.</p>
<p>“the question was that (3,5) was a point on f(x) so which of the following points is part of f (x-1)?”</p>
<p>Wait… (3,5) was NOT the given point on there… was it?</p>
<p>I thought (3,5) was the answer.</p>
<p>oh, i thought the point given was (3,5), hopefully i didn’t make that mistake on the test</p>
<p>do you know if (3,5) was choice b</p>
<p>Hmm, maybe i switched things around. Oh well. The idea’s there 
and I’m pretty sure I chose choice B, yeah.</p>
<p>Okay, new question: What was the given point on the graph?</p>
<p>Okay, well, from my reasoning: </p>
<p>the given had to be (2,5) for the answer to be (3,5)</p>
<p>if y= f(x) or (2,5) point
then y = f(x-1) is going to shift to the right to (3,5) yes?</p>
<p>wait can someone type up the actual union set question</p>
<p>okay, so (1,5) was choice D and (3,5) choice B or something? Was (1,5) even a choice at all?</p>
<p>i think (1,5) was a chioce, but it was wrong.</p>
<p>Does anyone remember what they got 33 for?</p>
<p>pliskin is a homoo</p>
<p>for the sequnce question with the 1, 4, 7, 10 … wasn’t the answer 60 if it was the difference between the 40th and 20th term how come these people are saying 36</p>
<p>Because it was the difference between the 40th and 28th term. Not the 20th term.</p>
<p>the answer is 36 because the 28th number is 82 and the 40th number was 118</p>
<p>118-82=36</p>
<p>for that question with the 40th term and 28th term, does anyone remember if “35” was an answer choice? I’m afraid I did 117-82 instead of 118-82.):</p>
<p>No i dont think 35 was a answer choice… i might be wrong but i thought the answers were far apart in numbers</p>
