Mr. Fjelstrom's Algebra 2

Stumbled on your site by accident. Just wanted to say that I think it's awesome you've used a blog to keep your students and parents up to date on the happenings of the course!

Thanks for the complement.

Today I learned that to find the inverse, you have to use 4 steps.

1. Change F(X) to Y
2. Switch X and Y
3. Solve for Y
4. Write inverse

I really like these function operation problems, they are easy for me because I can apply everything I have learned thus far in the year. I am looking forward to Friday - I feel confident I will do well on the benchmarks and hope to make up the last test we took in class.

What we learned today was easy yet difficult. The adding and subtracting weren't bad but the inverse is quite difficult. One little mistake can make it much harder.

In class we learned Functions, compositions, and Inverses for ex) f(x)=xsquared+3x-1 & y(x)=2xsquared-7x find f+g xsquared+3x-1 + 2xsquared-7x*3xsquared-4x= 3xsquared-4x-1.

You know, rather than writing out "squared", etc, you can use the ^ key (shift 6). So 2xsquared becomes 2x^2.

I learned about functions today and there can't be a x of f
