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 LeilaPiazza

I am a wife and mother. I am an Orthodox Christian. I am a Syrian American with family living in Syria. I am a also a yoga teacher and freelance writer. I recently described myself in a job pitch as "a person who's lived in Portland, Oregon for over 20 years with a passion for writing and a passion for all things Portland. I'm a foodie, knitter, wine and beer lover, bee-keeper (yep, I said it), mead and fruit-liqueur maker, organic gardener, home-canner, hiker, biker, runner, and occasional skinny-dipper. I’ve camped all over the state, I sail a sailboat that’s moored on the Columbia (o.k., I'm the first mate), and I spend a large percentage of my time at our beach house in Seaside." That about sums it up.
