Question

Dadas as funcoes F(x) =x² -6x-4 e G(x) =-2x²-5x+1 calcule:
A) f(3)
B) f(-2)
C) g(0)
D) g(1)

Answer 1

Resposta:

A) F(3) 1²-6.3-4

= 1.1-18-4

= 1-22

= -21

B) F(-2) 1²-6.(-2)-4

= 1.1+12-4

= 1+8

= 9

C) G(0) -2.1²-5.0+1

= -2.1+1

= -2+1

= -1

D) G(1) -2.1²-5.1+1

= -2.1-5+1

= -2-4

= -6
