9. 0/1 points details my notes scalc9 3.3.501.xp.mi. the graph of the second derivative f of a function f is shown. state the x - coordinates of the inflection points of f. (enter your answers as a comma - separated list.) x = 2,6,9 need help? read it master it submit answer
Answer
# Explanation:
## Step1: Recall inflection - point definition
Inflection points of a function $f(x)$ occur where $f''(x)$ changes sign.
## Step2: Analyze the graph of $f''(x)$
Look for the $x$ - values where the graph of $y = f''(x)$ crosses the $x$ - axis or has a discontinuity in concavity. From the graph, $f''(x)$ changes sign at $x = 3,7$.
# Answer:
3,7
