Show

CAS calculators find these in polynomial applications

Maximum and minimum values

Why domain restrictions exist in polynomial applications

Based on physical constraints of real-world situation

Volume formula for box from 12 cm square with cuts xx

V=x(122x)2V = x(12-2x)^2

Why x6x \leq 6 for 12 cm square box problem

Otherwise cuts would overlap

Maximum volume of box from 12 cm square sheet

128 cm³

Value of xx giving maximum volume in 12 cm box problem

2 cm

General form of cubic function

f(x)=ax3+bx2+cx+df(x) = ax^3 + bx^2 + cx + d

Systems of equations determine these in polynomials

Coefficients

Maximum deviation from axis means

Largest absolute value of function over interval

Why check if solutions are physically meaningful

Not all mathematical solutions fit real-world constraints
