. Which of the following statements about the function given by
f(x) = x4 – 2x3 is true ?
A) The function has no relative extremum.
B) The graph of the function has one point of inflection and the function has
two relative extrema.
C) The graph of the function has two points of inflection and the function has
one relative extremum.
D) The graph of the function has two points of inflection and the function has
two relative extrema.
E) The graph of the function has two points of inflection and the function has
three relative extrema.

Answer 1

calculus?

Answer 2

set the second derivative = 0 to find all the inflection point(s)
set the first derivative = 0 to find all the relative extrema
???
profit!

Answer 3

So would my answer be C.

Answer 4
