Well..
They are same in such... they both open downwards
They are different in... their y-intercepts are different, their x-intercepts are different.
Once you have them graphed you will see the exact values :)
Graph the quadratic functions
y = -2x^2 and y = -2x^2 + 4
on a separate piece of paper. Using those graphs, compare and contrast the shape and position of the graphs

They are also the same in that they both have a maximum value at a their respective vertices : )
