Question

dada a funcao do 1°grau F(x)=(1-5x) ,determine F(0),F(-1),F(1/5)F(-1/5

Answer 1

F(0) = 1 - 5.0
F(0) = 1 - 0
F(0) = 1

F(-1) = 1 - 5(-1)
F(-1) = 1 + 5
F(-1) = 6

F(1/5) = 1 - 5(1/5)
F(1/5) = 1 - 5/5
F(1/5) = 1 - 1
F(1/5) = 0

F(-1/5) = 1 - 5(-1/5)
F(-1/5) = 1 + 5/5
F(-1/5) = 1 + 1
F(-1/5) = 2
