Answer 1

f(x)=x
f(x)+4=x+4
if you let f(x)=y, then draw y=x
you get a straight line graph

Answer 2

y=x+5
would be a translation of 5 units in the positive y direction

Answer 3

so you have
f(x)=x
f(x)+3=x+3
so draw the graph y=x, then draw the graph y=x+3
then you will see that it was translated 3 units in the positive y direction

meaning, instead of crossing through (0,0) as it did for y=x
you now cross through (0,0+3)= (0,3)
so look for the graph that crosses this coordinate on the graph

an easier way to remember is
f(x)=x+b
then it will cross the point (0,b)

Answer 4

So it is graph 3?
