Basically I need a function f(x) which will rise slower as x is increasing. The x will be in range of [0.10 .. 10], so f(2x) < 2*f(x) is true. Also if. I would also like to have some constants which can change the way/speed the function is concaving.

WebNow that we know the intervals where f f is concave up or down, we can find its inflection points (i.e. where the concavity changes direction). f f is concave down before x=-1 x = −1 , concave up after it, and is defined at x=-1 x = −1 . So f f has an inflection point at x=-1 x = −1 . f f is concave up before and after x=0 x = 0 WebWhen f ′ ′ ( x) is negative, f ( x) is concaving downward. Similarly, when f ′ ′ ( x) is positive, f ( x) is concaving upward. From the table, we can see that f ( x) is concaving downward within the interval of ( − ∞, 4). The function is concaving upward within the interval of ( 4, ∞) .
