Question

Dada à função do 1º grau F(x) = (1 - 5x). Determinar:

a f(0)
b f (-1)
c f ( 1/5)
d f (-1/5)

agora marque a alternativa correta :
a) 1, 6, 0, 2

b)1, 4, 0, 1

c) 1, 6, 1, 1

d) 1, 4, 0, 2

​

Answer 1

Resposta:

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

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

alternativa correta: a) 1, 6, 0, 2
