Finding critical points
WebNow we look at the critical points and the endpoints of the interval: On the closed interval -3 \leq x \leq 3 −3 ≤ x ≤ 3, the points (-3,9) (−3,9) and (1,-7) (1,−7) are relative minima and the points (-2,20) (−2,20) and (3,45) (3,45) are relative maxima. Webf (x, y) = x^2 - 3xy - 1 f (x,y) = x2 − 3xy − 1 What are all the critical points of f f? Choose 1 answer: (-1, 1) (−1,1) A (-1, 1) (−1,1) \left ( 1, 0 \right) (1,0) B \left ( 1, 0 \right) (1,0) (0, 0) (0,0) C (0, 0) (0,0) There are no critical points. D There are no critical points.
