# In each part state the x-coordinates of the inflection points of f. Give reasons for your answers.(a) The curve is the graph of f.(b) The curve is the graph of f′.(c) The curve is the graph of f″. (a)

To determine

To state: The x-coordinates of the inflexion point of f.

Explanation

Given:

The given curve is the graph of f.

Definition used: Inflection point

A point P on a curve under the function f(x) is called an inflection point if f is continuous and curve changes from concave upward to concave downward or from concave downward to concave upward at P.

Reason:

Since the curve is the graph of f and from the given graph, it i

(b)

To determine

To state: The x-coordinates of the inflexion point of f.

(c)

To determine

To state: The x-coordinates of the inflexion point of f.
