30 points! inflection points question. okay, so i know that an inflection point is where the function is continuous and the concavity 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.
