CCSS.HSF.IF.A.2

Cosets always form a group. This statement is ________.

• True

• False

In comparing groups such as G and H, you should have a function f: G → H, where f(x⋅y)=f(x)⋅f(y). Operation in LHS is for the first group and the operation in the RHS is for the second group. They do not have to be the same. (I just cannot find a symbol appropriate from the formula option of the Quizizz.)

• True

• False
