Answer #1: x= 250
50 = x times 20/100
X= 100 times 50/ 20
X=250
Answer #2: same explanation but the answer is X= 120
If your talking about merging the percentage of the answer, I can’t help you with that
The domain is the x value: (-3)
The range are the y values: (0, 1, 2, 3) in order from least to greatest
No this is not a function because that value of x is "reused". You can "reuse" a y value with different x values but you can't reuse an x value ever, even if the y's are different. x's cannot be the same
I think it’s f(x+k) = f(x) + k correct if I’m wrong
The answer is the last one, y = 2/3 -2
