first function is f(x)= x+4
We make a table, plug in some numbers for x and find out y
x y= x+4
-4 0
3 7
Then graph the table using points (-4,0) and (3,7)
Second function is f(x)= 2x - 1
We make a table, plug in some numbers for x and find out y
x y= 2x - 1
3 5
6 11
Then graph the table using points (3,5) and (6,11)
