# graph of 1/x+1 look like watch

1. how does the graph of 1/x+1 look like
2. Try putting it into this website http://rechneronline.de/function-graphs/
3. It looks like the graph of 1/x translated by one unit to the left (negative x direction).
4. Is that 1/(x+1) or (1/x) + 1?
5. (Original post by Mathematician!)
Is that 1/(x+1) or (1/x) + 1?
1/(x-1)
6. Minus? If so it's 1/x translated to the right by one unit.
7. For rational functions in the form y = ax+b / cx+d
Equation for the vertical asymptote is the zero of the denominator (i.e -d/c)

And the equation for the horizontal asymptote is equal to a/c ( notice that a is the coefficient of x, so when x doesn't exist in the numerator, the horizontal asymptote = zero )

Find the asymptotes and draw you graph.
8. Let f(x) = 1/x. Then what is 1/(x-1) in terms of f(x)? Use this to find the translation of f(x).
