has critical points wherever the partial derivatives vanish:
Then
- If
, then 
; critical point at (0, 0) - If
, then 
; critical point at (1, 1) - If
, then 
; critical point at (-1, -1)
has Hessian matrix
with determinant
- At (0, 0), the Hessian determinant is -16, which indicates a saddle point.
- At (1, 1), the determinant is 128, and
, which indicates a local minimum. - At (-1, -1), the determinant is again 128, and
, which indicates another local minimum.
Answer:
f(9) = 72
Step-by-step explanation:
This is a piecewise function. You have to establish what part to plug in your x value based on the designations given in the function. In this case, x=9.
9>6, so we would follow the bottom designation! When writing the function, turn every "x" into a 9.
f(x) = 8x
f(9) = 8(9)
f(9) = 72
Hope this helps you out :)!
Answer:
The total cost of the salad is $59.50
Step-by-step explanation:
If each salad irrespective of there type costs $8.50
and Ellie ordered 5 tuna and 2 chicken salad, that
5+2 = 7 salads
Then the total cost of the salad will be
7*8.50 = $59.50
To solve both of these expressions, we want to add or subtract from left to right.
For the first one, we can rewrite it as:
8-6-9
=2-9
=-7
The second one we can rewrite as:
5-7+9+8-4
=-2+9+8-4
=7+8-4
=15-4
=11
