A1=5 an=an−1−3 which sequence is represented by the given information? {5,8,11,14} {5,2,−1,−4} {5,4,3,2} {0,−3,−6,−9}

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
