Which operation is not closed for polynomials? a) −(x2 + 4x + 5)(8x2 + 3x + 4) b) (7x2 + 2x + 3) + (3x2 − 5x + 4) c) (x2 + 2x + 5) − (x2 − 2x + 9) d) (x3 + 4x − 5)/(x5 − 2x + 2)

D is the answer, Since D is division and polynomials are not closed under division. 

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
