On which intervals is f concave down

WebAnswer: f (x) is concave up when x < −1/2 and concave down when x > −1/2. Let's solve this step by step. Explanation: Given that, f (x) = – (2x 3) – (3x 2) – 7x + 2 The first derivative of f (x): d/dx (–2x 3 – 3x 2 – 7x + 2) = −2 (3)x 2 −3 (2)x −7 = −6x 2 − 6x − 7 f' (x) = −6x 2 − 6x − 7 The second derivative of f (x): WebConcave downward, downward, is an interval, or you're gonna be concave downward over an interval when your slope is decreasing.
