Question

4) Dada a função do 1° grau fox)-1-5x, determine a) f(0)
b) f (-1)
c) f (1/5)
d) f (-1/5)
e) f (8)
f) f (13)
g) f (12)​

Answer 1

Resposta:

Explicação passo a passo:

f(x) = -1 - 5x

a) f(0)

f(0) = -1 - 5 . 0

f(0) = -1 - 0

f(0) = -1

b) f (-1)

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

f(-1) = -1 + 5

f(-1) = 4

c) f (1/5)

f(1/5) = -1 - 5 . 1/5

f(1/5) = - 1 - 1

f(1/5) = -2

d) f (-1/5)

f(-1/5) = - 1 - 5 . (-1/5)

f(-1/5) = - 1 + 1

f(-1/5) = 0

e) f (8)

f(8) = - 1 - 5 . 8

f(8) = -1 - 40

f(8) = - 41

f) f (13)

f(13) = - 1 - 5 . 13

f(13) = - 1 - 65

f(13) = - 66

g) f (12)​

f(12) = - 1 - 5 . 12

f(12) = -1 - 60

f(12) = -61
