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