minimum or maximum
axis of symmetry is x=-4
minimum value -2
I think you messed up when trying to find the axis of symmetry. There's a small calculation error there and it seems to have thrown off all your answers. However, your work overall is correct.
when you used the calculator to find (-8)/(2)(2) you did not consider the order of operations you must multiply 2 by 2 before you divide -8 by the answer, otherwise your method is correct
My range changes to -10 and the axis is x=-2, and min value is -10?
