Which statement is true?
If f ′(c) = 0, then f has a local maximum or minimum at (c,f(c)).
If f ′′(c) = 0, then the graph of f has an inflection point at (c,f(c)).
If f is differentiable at x = c, then f is continuous at x = c.
If f is continuous on (a,b), then f attains a maximum value on (a,b).
The graph of f ′ is shown above. Which statement(s) about f must be true
for a < x < b?
f is increasing.
f is continuous.
f is differentiable.
