What is the domain?
Hint (a):
Division by $0$ is undefined, so what value of $x$ must be excluded from the domain?

What happens as $x → −5$ ?
Hint (b):
What special feature does the curve have at $x = 5$ ?

What happens as $x → ∞$ ?
Hint (c):
This is the horizontal asymptote.

What happens as $x → −∞$ ?
Hint (d):
