Hi,
Identify the vertices and foci of the hyperbola. (4 problems-same type)
a. {{{y^2/16 - x^2/36 = 1}}} Opens Up and Down C(0,0), V(0,-4),V(0,4)and F(0, ± {{{sqrt(52)}}})
b. 9x^2 - 25y^2 = 225  
  {{{x^2/25 + y^2/9 = 1}}}Opens Right & Left C(0,0) ,V(-5,0),V(5,0)and F(±{{{sqrt(34)}}}, 0)
c. {{{(y+5)^2/36 - (x+2)^2/25 = 1}}}Opens Up and Down C(-2,-5) ,V(-2,-11),V(-2,1)and F(-2, -5±{{{sqrt(61)}}})
d. {{{x^2/25- (y-2)^2/4 =1}}} Opens Right & Left C(0,2) ,V(-5,2),V(5,2)and F(±{{{sqrt(29)}}}, 2)
