Question

Dada a função do 1° grau F(x)=(1-5x). Determine:

a)F(0)
b)F(-1)
c)F(1\5)
d)F(-1\5)

Answer 1

a) f(0) = 1 - 5x0
f(0) = 1

b) f(-1) = 1 - 5(-1)
f(-1) = 1 + 5 = 6

c) f(1/5) = 1 - 5(1/5)
f(1/5) = 1 - 5/5 = 1 - 1 = 0

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

Answer 2

equação: 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)=\1-1
f1/5)=0

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

espero ter te ajudado!!!
