(saddle point at P). Example (1) : Find and classify the critical points of f(x,y) = x2+4xy+2y2+4x−8y+3. Solution: Compute f x = 2x+4y+4 and f y = 4x+4y−8. Solve f x = 0 and f y = 0 to get the only critical point (6,−4). Note that f(6,−4) = 31. Compute f xx = 2,f xy = 4 and f yy = 4, and so ∆ = (2)(4) − 42 < 0 at any point.

(1 point) Find and classify the critical points of \( f ( x ) = 3 x ^ { 8 } ( 4 - x ) ^ { 7 } \) as local maxima and minima.. Critical points: \( x = \) Classifications: (Enter your critical points and classifications as comma-separated lists, and enter the types in …

To find and classify critical points of a function f(x) ... Find the critical points by setting f ' equal to 0, and solving for x .

You didn't ask for this, but we can also classify these critical points as follows: 1) Find the second-order partials: ∂ ...

Now, at any of the four critical points your function will have either a local minimum or a local maximum. So, the ordered pairs (0,2), (0,-2), (2,2), (2,-2) are all critical points of the two-variable function. Does that make sense or is there still something unclear?
