There are 2 steps to solve this one. Details. To visualize the idea of concavity using the first derivative, consider the tangent line at a point. Recall that the slope of the tangent line is precisely the derivative. As you move along an interval, if the slope of the line is increasing, then is increasing and so the function is concave up. Similarly, if the slope of the line is ... Graphically, a function is concave up if its graph is curved with the opening upward (Figure 1a). Similarly, a function is concave down if its graph opens downward (Figure 1b). Figure 1. This figure shows the concavity of a function at several points.

Concavity describes the shape of the curve of a function and how it bends. The curve can be concave up (convex down), concave down (convex up), or neither. Concave-Up & Concave-Down: the Role of \(a\) Given a parabola \(y=ax^2+bx+c\), depending on the sign of \(a\), the \(x^2\) coefficient, it will either be concave-up or concave-down: \(a>0\): the parabola will be concave-up \(a<0\): the parabola will be concave-down Concave-Up & Concave-Down: the Role of \(a\) Given a parabola \(y=ax^2+bx+c\), depending on the sign of \(a\), the \(x^2\) coefficient, it will either be concave-up or concave-down: \(a>0\): the parabola will be concave-up \(a<0\): the parabola will be concave-down

The second derivative is f'' (x) = 30x + 4 (using Power Rule) And 30x + 4 is negative up to x = −4/30 = −2/15, and 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. Note: The point where it changes is called an inflection point.Consequently, to determine the intervals where a function \(f\) is concave up and concave down, we look for those values of \(x\) where \(f''(x)=0\) or \(f''(x)\) is undefined.
