(-2,-1)
(4,-4)
I A. y - 2 = -0.5(x - 1)
B. y + 4 = -0.5(x - 4)
C. y = -0 5x-2
D. Y + 1 = -0.5(x + 2)

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
