Dada a função F (x)= 1-5x cálcule :


a) F (o)
f(x) = 1 - 5x
f(0) = 1 - 5(0)
f(0) = 1 - 0
f(0) = 1

b) F (-1)
f(x) = 1 - 5x
f(-1) = 1 - 5(-1)
f(-1) = 1 + 5
f(-1) =  + 6



c) F (1)
--
5

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

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

f(1/5) = 1 - 1

f(1/5) = 0


d) F (1)  ?????   IGUAL A (C)
5
