a. The graph is concave up. b. The graph is changing in direction at $x=3 $ and has minimum at $x=2$ with $S(3)=2$ c. $S(x)$ is increasing for $x>3$ and decreasing for $x<3$

From the given graph, we get a. The graph is concave up. b. The graph is changing in direction at $x=3 $ and has minimum at $x=2$ with $S(3)=2$ c. $S(x)$ is increasing for $x>3$ and decreasing for $x<3$
