You actually neded to MAKE a graph or tell me how to make it like where the lines go.

For the first equation
y = x + 4
the slope is 1
the y-intercept is 4
so your first point on the graph will be at (0, 4)
because x is greater than or equal to -4, but less than 3, you need to plug these numbers in to the equation y = x + 4 to get y
x: -4, -3, -2, -1, 0, 1, 2
y:   0, 1, 2, 3, 4, 5, 6
then you just plug those into the graph, so you start with (-4, 0), then (-3, 1), etc

for the other equation, do the same thing
y = 2x - 1 
slope is 2
y-intercept is -1
so you begin at (0, -1)
x: 3, 4, 5
y: 5, 7, 9

hope this makes sense
basically, the equation if f(x)=x+4 for all values of x where -4≤x<3
but it is f(x)=2x-1 for all values of x where 3≤x<6

≤ means less than or eqal to
so just graph the line y=x+4 from x=-4 to x=3, but put an open circle at x=3
wait, since it's a line, graph the endpoints
f(-4)=0
f(3)=7
graph the points (-4,0) and (3,7)
connect them
put an empty circle around the point (3,7)

now the other function
y=2x-1
from 3 to 6
f(3)=5
f(6)=11
graph the points (3,5) and (6,11)
connect them with a line
since we have the < sign with the 6, put an empty circle around the point (6,11)
see graph below
black line is first function (x+4)
red line is 2nd function (2x-1)
