Suppose that $f$ is given for $x$ in the interval $[0,12]$ by

A. Estimate $f'(2)$ using the values of $f$ in the table.
$f'(2)\approx$

B. For what values of $x$ does $f'(x)$ appear to be positive?

(Give your answer as an interval or a list of intervals, e.g., (-infinity,8] or (1,5),(7,10) .)

C. For what values of $x$ does $f'(x)$ appear to be negative?

(Give your answer as an interval or a list of intervals, e.g., (-infinity,8] or (1,5),(7,10) .)
