How do you graph #y^2/16-x^2/4=1# and identify the foci and asympototes?
The foci are
And the asymptotes are
The graph is a hyperbola "opens up and down"
graph{(y/4)^2-(x/2)^2=1 [-40, 40, -20, 20]}

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- How do you find the coordinates of the vertices and foci and the equations of the asymptotes for the hyperbola #(y+6)^2/20-(x-1)^2/25=1#?
- A hyperbola's center is at (1,-3). a^2 is 4 and b^2 is 16. How would I know if the hyperbola is horizontal or vertical? Can't it be both?
