Help me with graphing parabolas

failed a unit test retaking it but I don't know how to do some of the questions please help explain..

y = ( x + 2)^2 -3 its not in y = a ( x - h)^2 + k so I don't use h,k for my min or max value and axis of symettry point on the graph. {ps question if I did if the question represented itself as y = 3/4 ( 2 - 2)^2 + 3 , would my x,y be negative 2 and 3 (-2,3) ... or is it supposed to become a positive (2,3)

so y = ( x + 2)^2 -3 the equasion is also not in y=ax^2 + c so I don't use x= -b/2(a) to find x either...I'v looked through book examples .. how do I solve this? Also Its algebra 2 translating parabolas nothing too fancy please..I messed up on my test this way because I saw problems like these and saw no a and pretty soon I dropped a completly on all my graphing problems when using the vertex form. y = a ( x - h)^2 + k How am I supposed to solve this for my test if y = ( x + 2)^2 -3 has no a ?

Thanks

edit: please tell me if I can make this any more clear and I don't need to see the graph just how to get up to that point
