Concave interval calculator.

A critical point is when the derivative equals 0. And while it is always negative where you indicated, the derivative itself is increasing at one point. A much easier example to see this is -x^2. if this were the derivative of something, this also has a critical point at (0,0).Now use this to divide out your intervals into two intervals. (−∞, 0) ( − ∞, 0) and (0, ∞) ( 0, ∞). Pick a test point on each interval and see whether the f′′(testvalue) f ′ ′ ( t e s t v a l u e) is positive or negative. If it's positive then that mean f f is concave up in that interval, and if it's negative then it's ... Analyze concavity. g ( x) = − 5 x 4 + 4 x 3 − 20 x − 20 .
