**Problem 3** Consider the function \( f(x) = 2x^3 + 3x^2 - 7 \) (the same function as in problem 2). **a)** Find the intervals where the graph of \( f(x) \) is concave up, and where it is concave down. **b)** Find any inflection points. (Note: Since this is a transcription from an educational text, ensure you understand the concepts of concavity and inflection points when applying them to functions.)
