Question

Dada a função quadratica de lei f (x) = 1/2 + x/3 + x elevado a 2. Calcule: f (3/4)

Answer 1

1/2 + 3/4/3 + (3/4)²
 Simplifique a fração complexa

1/2 + 1/4 + (3/4)²
1/2 + 1/4 + 9/16

8 + 4 + 9/16

21/16

Answer 2

Boa noite Vitoria

f(x) = x² + x/3 + 1/2

f(3/4) = 9/16 + 3/12 + 1/2
f(3/4) = 9/16 + 1/4 + 1/2
f(3/4) = 9/16 + 4/16 + 8/16 = 21/16
