Below is the graph of f'(x), the derivative of f(x), and has x-intercepts at x = -3, x = 1, and x = 2 and a relative maximum at x = -1.5 and a relative minimum at x = 1.5. Which of the following statement is true? (5 points) (-1 5. 13.0) f is concave down from x = -1.5 to x = 1.5
f is concave up from x = 0 to x= 3.
None of these is true.
f has an inflection point at x = 0.​
