Question

Dada à função do 1° grau F(x) = (1 - 5x). Determinar:
a. F(0)
b. F(-1)
c. F(1/5)
d. F(-1/5)​

Answer 1

Explicação passo-a-passo:

F(x) = (1 - 5x)

a. F(0)

F(x) = (1 - 5x)

F(0) = 1 - 6.0

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

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

F(1/5) = 1 - 1

F(1/5) = 0

d. F(-1/5)

F(x) = (1 - 5x)

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

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

F(-1/5) = 1 + 1

F(-1/5) = 2
