I'm a bit surprised that I'm essentially the only one who comments with prospective answers.

Anyway, I'm back for more mathematical exercises.

The algebra question is C, the geometry is B, and the calculus is B.

Pretty simple ones this time, and I'm feeling fairly confident about these answers.

Algebra: Correct!
Geometry: Correct!
Calculus: Not quite...

My attempt:

Algebra I: C
Pythagorean Question: B
Calculus I: A

I see, the function is not smooth on this one at point a.

Algebra: Correct!
Geometry: Correct!
Calculus: Correct!

Nicely done!
