How many inflection points does the function f (x) have?



The graph of the function \( f(x) \) appears to have several points where the concavity changes. Inflection points occur where the second derivative \( f''(x) \) changes sign, meaning the curve changes from concave up to concave down or vice versa.

From the graph, I can visually identify two changes in concavity:
1. Near \( x = -2 \) (the curve changes from concave down to concave up).
2. Near \( x = 2 \) (the curve changes from concave up to concave down).

Thus, the function \( f(x) \) appears to have **two inflection points**.

Would you like further clarification or details on how to find inflection points analytically?
