Question

Dada a função do 1°grau f (x)=1-5x calcule :
a) F(0)

b)F (-1)

c)F(1÷5)

d)F (-1÷5)

Answer 1

a) f(0)= 1-5*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)= 0

d) f(-1/5)= 1-5*(-1/5)
f(-1/5)= 1+5/5
f(-1/5)= 5/5+5/5
f(-1/5)= 10/5
f(-1/5)= 2

Answer 2

Resposta:

a) f(0)= 1-5*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)= 0

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

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

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

f(-1/5)= 10/5

f(-1/5)= 2
