Answer 1

Resposta:

2) Considerando a função f(x) = - 2x + 3, calcule:

a) f(-3) = -2.(-3) + 3 = 6 + 3 = 9

b) f(- 6) =-2.(-6)+3= 12+3=15

c) f(10) =-2.10+3=-20+3=-17

d) f(15) =-2.15+3= -30+3=-27

e) f(13) =-2.13+3=-26+3= -23

f) f(15) =-2.15+3=-30+3= -27

g) f(-23) =-2.-23 +3= 46+3= 49

h) f(-53) =-2.-53+3=106+3=109
