Afriend uses the distributive property to simplify 4(2b-5) and gets 8b - 5 as the result. describe and correct the error.

well it would be 8b - 20 because you have to multuply by 4 on 5 too not just 2b

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
