Question

Dada à função do 1° grau F(x)= (1-4x). Determine;
a) F(0) B) F(-1) C) F(1/4) D) F(-1/5)

Answer 1

f(x)=(1-4x)
a) f(0)= 1-4.0
f(0)=-3.0
f(0)=0
b) f(-1)=1-4.(-1)
f(-1)=-3.(-1)
f(-1)=3
c) f(1/4)=1-4.1/4
f(1/4)=-3.1/4
f(1/4)= -0,75
d) f(-1/5)= 1-4.(-1/5)
f(-1/5)=-3.1/(-1/5)
f(-1/5)=-3/(-1/5)
f(-1/5)=15
