Hi, 
{{{(x+3)^2/16-y^2/9=1}}}
Hyperbola opening right and left, C(-3,0) Vertices(-7,0) & (1,0)
 sqrt(16+9) = sqrt(25)= 5  Foci(-8,0) and (2,0)

{{{drawing(300,300,   -10,10,-10,10, grid(1),
circle(-3, 0,0.3),
circle(1, 0,0.3),
circle(2, 0,0.3),
graph( 300, 300,-10,10,-10,10,0, 3sqrt(((x+3)^2/16) -1),-3sqrt(((x+3)^2/16) - 1) ))}}}
