Human Resources | What is WRITTEN BY: Charlette Beasley Publis...Consequently, to determine the intervals where a function \(f\) is concave up and concave down, we look for those values of \(x\) where \(f^{\prime\prime}(x) = 0\) or \(f^{\prime\prime}(x)\) is undefined. When we have determined these points, we divide the domain of \(f\) into smaller intervals and determine the sign of \(f^{\prime\prime ...There is an inflection point at x=-1.75 and the function is concave down (nn) on the interval (-oo,-1.75), and it is concave up (uu) on the interval (-1.75,oo). Concavity and inflection points of a function can be determined by looking at the second derivative. If the second derivative is 0, it is an inflection point (IE where the graph changes concavity). If the second derivative is positive ...The final answer is that the function f (x) = xlnx is concave up on the interval (0,∞), which is when x > 0. f (x)=xln (x) is concave up on the interval (0,∞) To start off, we must realize that a function f (x) is concave upward when f'' (x) is positive. To find f' (x), the Product Rule must be used and the derivative of the natural ...

The first derivative is f'(x)=3x^2-6x and the second derivative is f''(x)=6x-6=6(x-1). The second derivative is negative when x<1, positive when x>1, and zero when x=1 (and of course changes sign as x increases "through" x=1). That means the graph of f is concave down when x<1, concave up when x>1, and has an inflection point at x=1.You'll get a detailed solution from a subject matter expert that helps you learn core concepts.
