I don’t know why Joey doesn’t like algebra.


Seriously. Every time I get a problem right, I’m like, “woohoo!”  And I feel so smart. What about that isn’t fun for him?

For instance:

4a. Let f(x) = 10-3x. Find the domain and range of f.

Answer: domain and range are all real numbers. Woohoo!

4b. Let f(x) = 10-3x. Find  f –1.

Answer: f –1(x)= -x+10/3.  Woohoo!

4c. Let f(x) = 10-3x. Find f –1 (f(3)).

Answer: f –1 (f(3)) = 3. Woohoo!

Finally… 4d. Let f(x) = 10 – 3x. Find f(f –1(2)).

Answer: f(f –1(2)) = 2!  (…woohoo!)

Maybe it’s the triumph of my 42-year-old brain over inverse functions. That’s probably something he can’t appreciate yet.

About Leila

I am a wife and mother. I am an Orthodox Christian. I am a yoga and fitness instructor and personal trainer. And I am a Syrian American with family living in Syria. My life is defined by my family, and right now, that means chronic worry and fear. Thank God for my faith and the support of my family and friends. I started this blog to talk about all sorts of things, but now I focus on Syria. Until this war is over, I, like all Syrians with a love for their country and their families, am a prisoner of this war, waiting to see what will be left after the dust settles. I pray for the safety of my family and for my country to survive and repair itself in the future. God willing.
