1. f (x) = 3x³ + 2x² + 3x - 1

2. g (x) = x² + 5 x + 2 ​

Answer 1

Respuesta:

1- f (x) = 3x³ + 2x² + 3x - 1

f (0) = 3 x 0³ + 2 x 0² + 3 x 0 - 1

f (0) = 3 x 0 + 2 x 0 + 0 - 1

f (0) = 0 + 0 + 1

f (0) = -1

2- g (x) = x² + 5x + 2

g (x) + ? = x² + 5x + ? + 2

g (x) + ? = x² + 5x + 25/4 + 2

g (x) + 25/4 = x² + 5x + 25/4 + 2

g (x) + 25/4 = (x + 5/2)² + 2

g (x) = (x + 5/2)² + 2 - 25/4

g (x) = (x + 5/2)² + 17/4
