Let f(x, y) = 1 + xy − 2x + y and let D be the triangular region in double-struck R2 with vertices (−2, 1), (−2, 5), and (2, 1). Find the absolute maximum and minimum values of f on D. Give all points where these extreme values occur. (Order your answers from smallest to largest x, then from smallest to largest y.)

answer: yes, he is correct

step-by-step explanation: 10x-1=59

                                              1-1=0     59+1=60

answer: i think the answer is etheir c or d but i don't know which one but have a good day!

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
