Calculate f(g(x)) and g(f(x)) for each pair of functions.
(note: the notation (fog)(x) and (g (x) mean the same thing, respectively.)
16. f(x) = 3x +7; g(x) = -4x - 11
17. f(x) = - 4x + 60; g
18. f(x) = 10x - 5; g(x
л in
19. f(x) = -x +4; g(x) = -x +6

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

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
