Question

y=x+3,domain:0,1,2,3,4,5

Answer 1

Domain is to be plugged into the x

When x = 0, y = 3
when x = 1, y = 4
when x = 2, y = 5
when x = 3, y = 6
when x = 4, y = 7
when x = 5, y = 8

Just add 3 to the x to get your y for this equation

hope this helps

Answer 2

Replace X with the domain 0,1,2,3,4,5 

$0+3=3$
$1+3=4$
$2+3=5$
$3+3=6$
$4+3=7$
$5+3= 8$

Your range will be $3,4,5,6,7,8$

Domain: $0,1,2,3,4,5$
Range: $3,4,5,6,7,8$
