Nettet95 This is an LP problem because each new fi is linear and each fi ≈ f(X) over some range of X. The LP solution will be u = f2(X) because it is less than f1 or f3 and, therefore, closer to f(X) when 3 ≤ X ≤ 10. So the max value of u = a2 + b2 (5). Note that in the range 0 ≤ X ≤ 3, f1 is the smallest and for X ≥ 10, f3 is smallest. Similarly we could minimize a convex … Nettet23. mar. 2024 · The logistic function is the familiar S-shaped curve that comes from solving the logistic growth equation.

NettetNo. Because the base of an exponential function is always positive, no power of that base can ever be negative. We can never take the logarithm of a negative number. Also, we cannot take the logarithm of zero. Calculators may output a log of a negative number when in complex mode, but the log of a negative number is not a real number.
