G(n) = n 2 + 4 + 2n h(n) = β3n + 2 find (g β h)(1)
Question
Answer:
This is multiplication.First find g(n)*h(n). Β It is (n^2 + 4 + 2n)*(-3n+2). Β You could now do the algebra, but you could also substitute 1 for n right now.
(g*h)(1) = (1 + 4 + 2)(-3 + 2) = (7)(-1) = -7 (answer)
Please, use " ^ " to indicate exponentiation. Β n 2 doesn't cut it.
