<p>Not an SAT problem just didn't know where else too post it!
This is probably easy for a lot of you but not for me haha</p>

<p>Thanks! :)</p>

<p>What are you supposed to solve?</p>

<p>I just need to simplify it. After the equal sign is the answer but I can’t figure out how to get there.</p>

<p>original thing</p>

<p>You still have not given anything for us to help you solve.</p>

<p>I’m assuming you’re supposed to simplify f(t-3)? If so, just replace x with t-3, expand stuff, collect like terms.</p>

<p>Okay sorry, let me try to explain better.
It’s function notation and they give <a href=“http://tutorial.math.lamar.edu/Class...es/eq0009M.gif[/url]”>http://tutorial.math.lamar.edu/Class...es/eq0009M.gif&lt;/a&gt; and they want you to simplify it with f(t-3). I replaced all x’s with (t-3) but i can’t figure out how to the answer (-t^2 +12t - 38).
I hope this helps a little more.
Thanks</p>

<p>Oh I got it.
