All you have to do to solve this problem is insert the integer for the variable in the expression.
So, instead of having the variable expression r+s+t, you would have the integer expression 26-12-8.
If you combine 26 and -12, you get 14-8.
If you subtract 14-8, you get 6.
Your final answer is a. 6.
Set both partial derivatives equal to zero and solve for
.
The Hessian matrix (matrix of second-order partial derivatives) for this function is
Now since
for any
, and
for any
, it follows by the second partial derivative test that the critical point
is the site of a local minimum of
. The value of the minimum is
.
