30 points! Inflection points question. Okay, so I know that an inflection point is where the function is continuous and the conc
avity changes. On the graph I attached, it is asking to: "Use the graph of f "(x) below to state x-coordinates of the inflection points for the graph of f(x)."
Am I supposed to find the concavity changes of f(x) or of f"(x)? Also, do I give the x coordinate or the y coordinate when writing my answer.

Answer:
a) There is suggestive evidence the velvet leaf seed is successful at weed control.
b) Lower bound: 3.699 Upper bound: 6.629
c) Since the confidence interval contains the average percent of seeds to be infected by the beetle (5.164), so we fail to reject the null hypothesis at the specified level of significance.
