Compute the plane tangent to the graphs at the indicated points using the given functions. (Let z be the dependent variable. If an answer does not exist, enter DNE.) (a) (0, 0)
(i) f(x, y)=xy
(ii) f(x, y)-eX
(iii) f(x, y) = x cos(x) cos(y)
(iv) fx, y) - (x2+ y2) log(x2 + y2)
(b) (0,1)
(i) f(x, y) = xy
(ii) f(x, y) = exy
(iii) f(x, y) = x cos(x) cos(y)
(iv) f(x, y)- (x2 + y2) log(x2 +y2)

the answer would be c:   ax + b = ax + c

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
