Use the second derivative test to find the local maximum and minimum values and saddle points of the function f(x, y) = 4x^3−2x^2 y +y^2 + 8y.

ahem is 5y+4

Step-by-step explanation:

90% rotation

step-by-step explanation:

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
