Homework for Lecture #9 This homework is due no later than 5pm, on the day of exam #2, along with all the other homeworks assigned prior to exam #2. You can hand them in in-class (before or after the exam), or you can drop them off in room 154 for me, or you can staple it to all the other homeworks that are due, and slide it under my office door (office #319) Section 2.1 2.4 Homework Problems (In the form #(answer) ) Identify Symmetry from a graph: (You don't have to do the intercept stuff) Identify Symmetry from an equation: (You don't have to do the intercept stuff) #17 (see back of book) #18 (none) #19 (see back of book) #22 (X-axis, Y-axis, and origin symmetry) #33 (see back of book) #34 (origin) #35 (see back of book) #36 (Y-axis) #41 (see back of book) #42 (X-axis, Y-axis, and origin symmetry) #11 (see back of book) #12 (no) #13 (see back of book) #14 (yes) #15 (see back of book) #16 { (-∞, -8) , (-2, 0) , (2, 5) } #25 (see back of book) #26 #21 (see back of book) #22 a: (-1, 0) (1,0) (0,2) x 3 x 3 range: y 0 y 3 b: domain: ,0 2 ,0 (0,1) 2 b: domain: x x a: y 1 y 1 c: increasing: ,0 decreasing: 0, range: d: even (y-axis symm) c: increasing: (-1, 0) (1, 3) decreasing: (-3, -1) (0, 1) d: even (y-axis symm) Keep in mind that for every homework assignment, you should do as many problems as you need to really have some confidence that you understand the material. If that means you do more than what’s here, that’s great.
