Function concave up and down calculator.

Solution: Since f′(x) = 3x2 − 6x = 3x(x − 2) , our two critical points for f are at x = 0 and x = 2 . We used these critical numbers to find intervals of increase/decrease as well as local extrema on previous slides. Meanwhile, f″ (x) = 6x − 6 , so the only subcritical number is at x = 1 . It's easy to see that f″ is negative for x ...Many of our calculators provide detailed, step-by-step solutions. This will help you better understand the concepts that interest you. eMathHelp: free math calculator - solves algebra, geometry, calculus, statistics, linear algebra, and linear programming problems step by step. When f''(x) is positive, f(x) is concave up When 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 increasing, so f''(x) is positive (and vice versa) Hope this helps! f(x) is concave on (-oo,-4.5) and (0,oo), and f(x) is convex on (-4.5,0). To find where a function is concave up, find where the second derivative of the function is positive. f(x)=-x^4-9x^3+2x+4 Find f'(x): f'(x)=-4x^3-27x^2+2 Next, find f''(x): f''(x)=-12x^2-54x f''(x)=(-6x)(2x+9) Set f''(x) equal to zero to find inflection points 0=(-6x)(2x+9) x=0, x=-4.5 After checking the signs of values ...Suppose that \(f''(a)>0\). This means that near \(x=a\), \(f'\) is increasing. If \(f'(a)>0\), this means that \(f\) slopes up and is getting steeper; if \(f'(a) < 0\), this means …

Use a number line to test the sign of the second derivative at various intervals.
