title: Big-O Notation, Find the Smallest
body: <p>Give the smallest O() estimate you can for the following functions:</p>
  
  <pre><code>4n2 + 5n – 8 = O(...)
  
  
  log(n)2 + n = O(...)
  </code></pre>
  
  <p>If you guys can, explain the answer rather than giving it to me. A question like this will be on my mid-term and I want to understand this.</p>
  
  <p>Thanks</p>
