8º) Dada a função definida por:
F (X) = 2x + 1

Calcular:
a) f (0) =
b) f (7) =
c) f (-2)=
d) f (-5)=​

Answer 1

a) f(x) = 2x + 1

f(0) = 2 . 0 + 1

f(0) = 0 + 1

f(0) = 1

b) f(x) = 2x + 1

f(7) = 2 . 7 + 1

f(7) = 14 + 1

f(7) = 15

c) f(x) = 2x + 1

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

f(-2) = - 4 + 1

f(-2) = - 3

d) f(x) = 2x + 1

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

f(-5) = - 10 + 1

f(-5) = - 9
