Question

Geometry help?? Please

Answer 1

The intersection of two sets, written
`A\cap B` is the set that contains all elements in BOTH of the original sets.

In this case:

`A\cap C=\{0,1,2,3\}\cap\{0,a,2,b\}=\{0,2\}`

Unless you are told somewhere else what a and b are equal to, none of the given choices is correct.
