Plot the graph of $f(x)=x^{3}-e^{x}$ using a graphing calculator or computer to find all local and global maxima and minima for: (a) $-1 \leq x \leq 4$ (b) $-3 \leq x \leq 2$
Using the Derivative
Global Maxima and Minima
$3-14$ Use Lagrange multipliers to find the maximum and minimum values of the function subject to the given constraint. $f\left(x_{1}, x_{2}, \ldots, x_{n}\right)=x_{1}+x_{2}+\cdots+x_{n}$ $x_{1}^{2}+x_{2}^{2}+\cdots+x_{n}^{2}=1$
Partial Derivatives
Lagrange Multipliers
$3-14$ Use Lagrange multipliers to find the maximum and minimum values of the function subject to the given constraint. $f(x, y, z)=x^{2} y^{2} z^{2} ; \quad x^{2}+y^{2}+z^{2}=1$
