A continuous function $f,$ defined for all $x,$ has the following properties:

$f$ is decreasing

$f$ is concave up

$f(9)=-4$

$f^{\text{'}}(9)=-\frac{1}{2}$

Sketch a possible graph for $f,$ and use it to answer the following questions about $f.$

A$.$ For each of the following intervals, what is the minimum and maximum number of zeros $f$ could have in the interval? $($Note that If there must be exactly N zeros in an interval, the minimum and maximum are both N$..)$
