Write a method in bag such that if b1 and b2 were bags then b1+b2 gives a new bag representing the union of the two bags.

The method to represent that if b1 and b2 were bags then b1+ b2 gives a bag representing the union of the two bags can be explained as follows:

a. input (b1)

a. input (b2)

b= Bag ( )

b.input ()

Print (b1+b2)

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

the first option is the answer.
