in the domain are the values of x
in the range are the values of y
if you substitute in the values of the domain x=0, x=1, x=3, x=5, x=6 in the function f(x)= y=4-4x you will get the value from the range y=4, y=0, y=-8, y=-16, y=-20
and so on...
Answers:
first f(x)=4-4x
second f(x)=5x-3
third f(x)=-10x
fourth f(x)=(3/x)+1.5
