Answer

We can see a sketch of one possible graph below.

Work Step by Step

$f'(x) \gt 0$ if $x \neq 2$ The graph is increasing on the intervals $(-\infty, 2)\cup (2, \infty)$ $f''(x) \gt 0$ if $x \lt 2$ The graph is concave up on the interval $(-\infty, 2)$ $f''(x) \lt 0$ if $x \gt 2$ The graph is concave down on the interval $(2,\infty)$ $f$ has inflection point $(2,5)$ The graph changes concavity at this point. $\lim\limits_{x \to \infty}f(x) = 8$ There is a horizontal asymptote at $y=8$ $\lim\limits_{x \to -\infty}f(x) = 0$ There is a horizontal asymptote at $y=0$ We can see a sketch of one possible graph below.
