Suppose that f ( x , y ) = x 2 − x y + y 2 − 3 x + 3 y , with domain d constrained by the lines y = x , y = 0 , and x = 3 . the critical point of f ( x , y ) restricted to the boundary of d , but not at a corner point, is at ( a , b ) , where a and b . the absolute minimum of f ( x , y ) is and the absolute maximum is 9 correct .

r = 78539458390583095803458309458039485093485 or just 3

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
