Determine concave up or down
WebJan 3, 2024 · For a general parabola, we first rotate the coordinate-axes to bring it to the above form by also parallelly shifting the axes, and then find the regions of its concavity. Assuming a parabola opens up or down (otherwise known as a quadratic function): If the coefficient of [math]x^ {2} [/math] is positive, it’s concave up. WebNov 16, 2024 · So, a function is concave up if it “opens” up and the function is concave down if it “opens” down. Notice as well that concavity has nothing to do with increasing or decreasing. A function can be …

WebWhen f''(x) is negative, f(x) is concave down When f''(x) is zero, that indicates a possible inflection point (use 2nd derivative test) Finally, since f''(x) is just the derivative of f'(x), when f'(x) increases, the slopes are … WebExample 5.4.1 Describe the concavity of f ( x) = x 3 − x . First, we compute f ′ ( x) = 3 x 2 − 1 and f ″ ( x) = 6 x . Since f ″ ( 0) = 0, there is potentially an inflection point at zero. Since f ″ ( x) > 0 when x > 0 and f ″ ( x) < 0 when x < 0 the concavity does change from down to up at zero, and the curve is concave down for ...
