Question

Given the graph of f ′(x), the derivative of f(x), which of the following statements are true about the graph of f(x)?

Answer 1

This is the derivitive of x
critical points are where the first derivitive is equal to 0 or where the derivitive doesn't exist

ok, it is 0 at x=0 and 2
so I is true but not II

the point of inflection is where the slope of the 1st derivitive=0
that is at x=1
so III is true


I and III
