2. Type of Graph Graphing can be really hard… Graphing can be really hard… Remember…circles have the same number for everything Remember…circles have the same number for everything And elipses are always positive And elipses are always positive Parabalas are or  faces, with only one number squared Parabalas are or  faces, with only one number squared Hyperbolas turn away from each other and are sad because they are negative Hyperbolas turn away from each other and are sad because they are negative

3. Circles x 2 + y 2 = 0 x 2 + y 2 = 0 a=1 b=1 a=1 b=1 Vertices: (1, 0) (-1, 0) Vertices: (1, 0) (-1, 0) Co-vertices: (0,1) (0,-1) Co-vertices: (0,1) (0,-1)

4. Elipses x 2 /16 + y 2 /4 =0 x 2 /16 + y 2 /4 =0 A 2 = 16A = +/-4 A 2 = 16A = +/-4 B 2 = 4B = +/-2 B 2 = 4B = +/-2 Vertices: (+/-4,0) Vertices: (+/-4,0) Co-vertices: (0, +/-2) Co-vertices: (0, +/-2)

5. Parabolas 5y 2 = 7x 5y 2 = 7x y 2 = -7/5x y 2 = -7/5x y 2 = left/right y 2 = left/right Negative=right Negative=right

6. Hyperbolas x 2 /16 -y 2 /4=0 x 2 /16 -y 2 /4=0 A 2 =16A=+/-4 A 2 =16A=+/-4 B 2 =4B=+/-2 B 2 =4B=+/-2 Vertices: (+/-4,0) Vertices: (+/-4,0) Co-Vertices: (0, +/-2) Co-Vertices: (0, +/-2) Asymptote=-b/a Asymptote=-b/a
