Question

gente me ajuda, dada a função f(x)=2x+1

Calcule A) f(0)
B) f(-2)
C) f(-5)

Answer 1

f(x) = 2x + 1

a)

f(0) = 2.0 + 1

     = 0 + 1

     = 1

b)

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

      = -4 + 1

      = -3

c)

f(-5) = 2.(-5) + 1

      = -10 + 1

      = -9

Answer 2

f(x)=2x +1
f(0)=2(0) +1 = 0 +1 = 1
f(-2)=2(-2) +1 = -4 +1 = -3
f(-5)=2(-5) +1 = -10 +1= -9
