If there are typos or mistakes, let me know so I can fix them here.
P1.
a) Set \( 9 - x^2 \geq 0 \) and solve either algebraically or graphically to find the domain: \( [-3, 3] \)
Algebraically, study the sign after factoring \( (3-x)(3+x) \geq 0 \).
Geometrically, draw the graph of \( y = 9 - x^2 \) to confirm the domain.
b) Set \( x^2 - 4 >0 \) and solve either algebraically or graphically to find the domain. The work is similar to part a).
The domain is: \( x < -2 \cup x > 2 \). In interval notation: \( (-\infty, -2,) \cup (2, \infty) \)
c) Set \((1-x)(5-x) > 0 \) and solve either algebrically or graphically to find the domain. The work is similar to part a).
The domain is: \( (1,5) \).
c) The domain of the direct sum of the three functions is the intersection of the domains in parts a), b), and c).
The intersection, using interval notation, is: \( (2, 3] \).

Welcome to AP Calculus BC. In this area of the course page we will post important course-related information such as links to resources, announcements, reminders, commentary or feedback on assessments etc. All entries will be dated and the most recent one will be at the top of the page. As far as daily course information goes, the Assignments and Bulletin tabs are the most important.
