The sequence can be a sequence of numerical values or sequence of computable expressions. Notice that the polynomial doesn't actually have a maximum or minimum value, because it keeps going both up and down forever. Simple Interest Compound Interest Present Value Future Value. The function has an absolute maximum of zero at \(y = - 4\) and the function will have an absolute minimum of -15 at \(y = - 5\). Differentiate the given function. Local and Global Extrema A local minimum/maximum is a point in which the function reaches its lowest/highest value in a certain region of the function. Simple Interest Compound Interest Present Value Future Value. 1. The minimum value of a function is found when its derivative is null and changes of sign, from negative to positive. Example: Calculate the maximum of the function $ f(x) = -x^2 + 1 $. Finding the minimum of a function $ f $, is equivalent to calculate $ f(m) $.

The minimum value of a function is found when its derivative is null and changes of sign, from negative to positive. You can put negative numbers if you need to use a negative coefficient. Tool to determine the minimum value of a function: the minimal value that can take a function. In that case, $ f(m) $ is the minimum value of the function, reached when $ x=m $. The minorant is any value lower than or equal to the minimum value reached by the function. For any function $ f $ defined on an interval $ I $ and $ m $ a real number belonging to $ I $, if $ f(x) <= f(m) $ on the interval $ I $ then $ f $ reaches its minimum in $ x=m $ over $ I $.
