The answer is A.  If you’ve had basic functions, then this question isn’t so bad.  Just substitute a for x.  That is, f(x) = f(a).  Therefore, 2x + 3 = 2a + 3 = 11.  Solving for a, you get 4.  Even if you haven’t had functions, you can see how you just substitute the value inside the parentheses for x.  See how easy that is?  Another thing to be thankful for!

Let’s see what the ACT folks have for us this morning.

Well, here’s something we can’t be thankful for!  It’s another question that we just saw a couple of weeks ago.  I’d be thankful if the ACT folks would use some new questions.

The answer is K.  To read the “math teacher” way, you should read what the ACT folks have to say about this question’s explanation.  It works but sure takes a long time.

I did it by understanding the denominator in the right side of the equation is an absolute value, which means y has to be positive.  The only answer that is a graph for when y is always positive is K, simple enough.  Why make it complicated?

Sorry about skipping out on you yesterday.  Along with the other “F’s” for Thanksgiving: family, friends, food, and football, I forgot one: fishing.  It was a great day.

Now I’m going to be waiting to watch FSU crush UF on the football field.  Unfortunately, we lost the basketball game last night when we missed a “hail, Mary” shot.  I think it will take more than a “hail, Mary” for UF to win the football game today.
