Apr 10, 2024 · An inflection point is where a function changes concavity and where the second derivative of the function changes signs. Take the first and second derivative of the function using the power rule. Set the second derivative equal to 0 to find the candidate, or possible, inflection points.
The derivative is y' = 15x2 + 4x − 3. The second derivative is y'' = 30x + 4. And 30x + 4 is negative up to x = −4/30 = −2/15, positive from there onwards. So: f (x) is concave downward up to x = −2/15. f (x) is concave upward from x = −2/15 on. And the inflection point is at x = −2/15. A Quick Refresher on Derivatives.

Feb 1, 2024 · To find inflection points of a function, you should first understand what an inflection point is. In calculus, an inflection point represents a location on the graph of a function where the concavity changes from upwards to downwards or vice versa.
Given a graph of f'(x), it is possible to find the inflection points of f(x) based on the relationships between f(x), f'(x), and f"(x): When f"(x) is positive, f'(x) is increasing, and f(x) is concave up. When f"(x) is negative, f'(x) is decreasing, and f(x) is concave down. When f"(x) is 0, f'(x) is not changing, and f(x) may have an ...
