Find the linearization L(x, y) of the function f(x, y) at the point P0.
Then find an upper bound for the magnitude of the error E in the approximation
f(x, y)≈L(x, y)
over the rectangle R.
f(x, y)=xy−3y2+2,P0(1,1) R:|x−1|≤0.1,|y−1|≤0.2

honestly bro aint no one got time to answer these dumb question just do it p***y

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
