Domain is always the first number of a function. So for this, it would be (0,3,5,8). But if you have more than one number in the same function than there is no need to "say" it twice. Hope it helps! :)
If 1/4x - 1/4 = 2 then 2 + 1/4 = 1/4x. so 3/4 = 1/4x 3/4 is equal to 1/1.33 (reduce by dividing both numerator and denominator by 3) so 4 x ? = 1.33. 1.33 / 4 = 0.3325 so (if you're solving for x) I believe the answer is x = 0.3325
