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
