(ENEM 2010). Um porta-lápis de madeira foi construido no formato cúbico, seguindo o modelo ilustrado a seguir. O Cubo de dentro é vazio. A Aresta do cubo maior mede 12 cm e a do cubo menor ,que é interno, mede 8 cm

For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585
