Question

dada a função do 1º grau f (x) = 1 - 5x. determinar :
a) f (0)
b) f(-1)
c) f ( 1/5)
d) f (-1/5)

Answer 1

f(x)= 1 - 5x
a) f(0) =  1 - 5.0
    f(0) = 1
b) f(-1) = 1 - 5(-1)
    f(-1) = 1 + 5
    f(-1)= 6

c) f(1/5) = 1 - 5(1/5)
   f(1/5) = 1 - 1
  f(1/5) = 0

d) f(-1/5) = 1 - 5(-1/5)
                  1 + 1
   f(-1/5) = 2
