Question

2) Dada a função f por f(x)=2x + 1 determine:
a) f(0)
b) f(-2)
c) f(3)
d) f(-4)
ajudem pvf!!!!!!!!!!!​

Answer 1

Resposta:

f(x)=2x + 1

___________

a) f(0) = 2 . 0 + 1 =

f(0) = 0 + 1 =

f(0) = 1

b) f(-2) = 2 . (-2) + 1 =

f(-2) = +4 +1 =

f(-2) = 5

c) f(3) = 2 . 3 + 1 =

f(3) = 6 + 1 =

f(3) = 7

d) f(-4) = 2 . (-4) + 1 =

f(-4) = +8 +1 =

f(-4) = 9
