You already graphed 3 and 4, 3 is the one you have graphed on the top and 4 is the one below it.
To graph #1 the vertex would be at -2 on the x axis and the y intercept would be 2
To graph #2 the vertex be at 2 on the x axis and the y intercept would be 2
Basically for #1 and #2 the plus and negative sign mean the opposite
