Question

2) Dada a função do 1o grau f(x) = (1 – 5x). Determine: 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)= 1 - 5.0

f(0)= 1 -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 - 5/5

f(1/5)= 1 - 1

f(1/5)= 0

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

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

f(-1/5)= 1 + 1

f(-1/5)=2
