Question 454107: Hi, I am studying for a quiz on hyperbolas and one of the problems I am doing is this:
Write an equation in standard form for each hyperbola.
Length of transverse axis 10 and foci at (-7,18) and (-7,-8)
So far, I understand that it is vertical therefore the equation would be in the (y-k)^2/a^2-(x-h)^2/b^2=1
I am pretty sure I also got the center which was (-7, 5)
So now I have (y-5)^2/a^2-(x+7)^2/b^2=1
My problem is is that I don't know how to find what a and b are. I understand they come from the vertices and co-vertices but I don't think I fully understand the transverse axis.

Question 455309: How do you solve domains of functions? For example,
f(x)=square root of (x-2)
f(x)=-5x/7+4
f(x)=1/x-2
There's the domain of f(x), the range of f(x), the equation of f^-1(x), the range of f^-1(x), and whether f^-1(x) is a function. How do I solve for each?
Thanks!
