Consider the function $\displaystyle f(x) = \frac { 2 x + 7 } { 6 x + 5 }$.

For this function there are two important intervals: $(-\infty, A)$ and $(A,\infty)$ where the function is not defined at $A$.
Find $A$:

Find the horizontal asymptote of $f(x)$:
$y=$

Find the vertical asymptote of $f(x)$:
$x=$

For each of the following intervals, tell whether $f(x)$ is increasing (type in INC) or decreasing (type in DEC).
$(-\infty, A)$:

$(A,\infty)$:

Note that this function has no inflection points, but we can still consider its concavity. For each of the following intervals, tell whether $f(x)$ is concave up (type in CU) or concave down (type in CD).
$(-\infty, A)$:
$(A,\infty)$:

Sketch the graph of $f(x)$ and bring it to class.
