Describe the graph of y = 1/(x + 1) - 2. Give the asymptotes, the domain and the range.

Try it on paper first. A hint, the key idea and the worked solution are here when you need them.

Describe the graph of $y = \dfrac{1}{x + 1} - 2$ . Give the asymptotes, the domain and the range.

Need a reminder? The key ideaShow

$f(x - h) + k$ moves the graph $h$ right and $k$ up; $a\,f(x)$ stretches the heights; $f(-x)$ and $-f(x)$ reflect it. Even: $f(-x) = f(x)$ . Odd: $f(-x) = -f(x)$ .

The worked solution

Have you tried it?

Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
