Explanation:
Domain is the x value and Range is the y value. (A way to remember is by saying dr since domain is x and range is y)
Y value is also called f(x) as shown on your screen
The points are
(1,-8)
(2,5)
(3,-2)
(4,1)
The domain would be 4,3,2,1 and the range would be -8,-2,1,5
The common difference is that the domain follows a constant change of rate, but not the range.
A constant change of rate means that it's changing at a constant rate.
It can also be called slope.
E.G: 1,2,3,4 (constant change of rate is adding 1) or 9,6,3,0 (subtracting 3)
The domain is subtracting 1, yet the range isn't following a constant change of rate.
A way to find slope is in the image.
