<p>I HATE problem 14. It's so stupid and I ALWAYS get stumped on this type of problem. I try subsituting, but it doesn't work.</p>
<p>You can look for 747 / 14 in <a href="http://talk.collegeconfidential.com/sat-preparation/339734-consolidated-list-blue-book-math-solutions-3rd-ed.html%5B/url%5D">http://talk.collegeconfidential.com/sat-preparation/339734-consolidated-list-blue-book-math-solutions-3rd-ed.html</a></p>
<p>747 #14</p>
<p>Questions 13 - 14 refer to the following functions g and h.
g(n) = n^2 + n
h(n) = n^2 - n
Which of the following is equivalent to h(m + 1)</p>
<p>Answer: A. g(m)</p>
<ul>
<li>Substitute (m + 1) for n in the function h(n) = n^2 - n. h(m) = (m + 1)^2 - (m + 1).</li>
<li>Simplify it. h(m) = m^2 + m</li>
<li>If you refer back to the top, this is equilavent to g(n) = n^2 + n; therefore h(m+1) is equivalent to g(m).</li>
</ul>
