Range of F from A to B
Approssima min e max della funzione F tra A e B / It approximates the min and max of the function F between A and B

Se abbiamo / if we have:

/// Min/Max of F from A to B. You can modify F, A, B

function F(x) {

y = 13*Math.pow(x,3) - 75*x

return y }

A = -4; B = 2.5

otteniamo / we obtain:
-4 <= x <= 2.5 ___ y Min ~_ -532 ___ y Max ~_ 69.33752379676837

(the "true" max is 69.3375245...)
